Careful water hammer control is essential to ensure reliable operation of hydropower plants. If this is not provided, severe problems may arise in operation, damage to individual components of the system may occur or, in the worst case, accidents with human casualties may happen [1] to [5]. Modelling and analysis of extreme hydraulic transients (plant emergency shut-down) in new or refurbished HPPs are of utmost importance because, in this way, extreme values of pressures that may occur during system exploitation can be determined. Based on these values, closing and opening times of the turbine units’ distributors are devised, as well as dimensioning of the system components is done. The objective of this paper is to investigate and discuss water hammer effects in Perućica HPP, Montenegro during the entire plant emergency shutdown, i.e., simultaneous closure of all seven Pelton turbine units. The units are installed in three parallel penstocks (each of about 2 km long) that are coupled to a concrete tunnel (about 3.3 km long) with a surge tank. Previously, measurements of the first and second Pelton turbines in one penstock only have been investigated [6]. This paper presents new results at much higher Reynolds number flows (higher than 107) than previously presented (in order of 106). In the first part of the paper, mathematical tools for solving water hammer equations are presented [7] and [8]. Friction losses in the plant’s penstocks are calculated with two different models: (1) standard quasi-steady (QSF) and (2) convolutionbased unsteady friction model (CBM) [9] and [10]. Turbine speed change during emergency shut-down is calculated, taking into account dissipative torques, including the shaft-bearing friction torque and ventilation losses in the turbine housing [6].

Sturm","doi":"10.5545/SV-JME.2019.6083","DOIUrl":"https://doi.org/10.5545/SV-JME.2019.6083","url":null,"abstract":"Aluminium alloys series 7xxx containing zinc, magnesium and copper, as the main alloy elements, are characterised by high ultimate tensile strength (UTS) between 350 MPa and 650 MPa, depending on the state of the alloy. For comparison, the extruded profiles from 6xxx alloys after heat treatment show the UTS at levels of 160 MPa to 340 MPa. Due to its high specific strength, formability, corrosion resistance, resistance to stress corrosion cracking, lightweight and wide application, the aluminium alloy 7075 is widely used in automotive and aerospace industries [1] to [4]. However, these alloys generally have poor ductility and low fracture strength in the as-cast condition, and extensive processing, which includes a combination of heat treatment and hot-cold working, is required to improve the mechanical properties [5]. González et al. [6] investigated different shot peening treatments with conventional and severe parameters, which were performed on an aluminium 6063 alloy in order to assess the differences induced in the microstructure of the surface layer and to evaluate their effects on fatigue behaviour. The obtained results evidence the notable influence of shot peening parameters on the surface layer microstructure, which simultaneously influence fatigue behaviour. Jamalian and Field [7] carried out a microstructural analysis of an AZ31 Mg alloy, which revealed a direct relation between the thickness of the ultra-fine grained layer and severe shot peening parameters, with each of them having a distinct effect on grain size. Furthermore, microhardness tests demonstrated how pressure and shot size control fine grains at the surface. Tensile test results revealed that the best mechanical properties were obtained by maximum shot size and pressure at minimum processing time. Nam et al. [8] investigated the effects of four peening parameters on microhardness and residual stress of AA 2124-T851. To verify the validity of the optimal conditions obtained from experimental results, metallurgical analyses of the shot-peened aluminium alloy were conducted with respect to hardness, residual stress, surface morphology, X-ray diffraction (XRD) analysis and surface roughness. They concluded that shot peening induces plastic deformation, increases surface hardness and introduces significant levels of compressive residual stress. Under optimal peening conditions, the average microhardness and compressive residual stress are ~13 % higher than that of the unpeened sample.

Lei","doi":"10.5545/SV-JME.2018.5938","DOIUrl":"https://doi.org/10.5545/SV-JME.2018.5938","url":null,"abstract":"Residual stresses are locked-in stresses that remain in solid materials after the removal of the external cause of stresses [1]. Residual stresses are induced in components during most manufacturing processes, such as material deformation, heat treatment, machining, or processing operations that transform the shape or change the properties of the material [1]. They develop when a body undergoes inhomogeneous plastic deformation or is exposed to a non-uniform temperature distribution, such as in the case of welding, warm forming, casting, and quenching processes [2] to [4]. A material’s ability to resist fatigue, and crack initiation and propagation at ambient temperature, brittle fracture, machining distortion, and corrosion cracking is adversely affected by residual stresses [3] and [5] to [7]. These effects regularly cause significant costs of repairs or replacement of parts [5]. Analysis of residual stresses is considered as one of the necessary steps in the design of structural elements and components, which aid in predicting their reliability under different loading conditions during operation [6]. Extensive studies revealed that the fatigue strength of welded elements is drastically reduced due to high residual stresses induced at the weld bead and heat-affected zone (HAZ) [8] and [9]. Webster et al. reported that residual stress, which can be in excess of the yield strength of the material, could develop at the HAZ: is the region near the weld zone that is not melted during welding, but its properties have been severely altered due to the effect of the welding torch [10] to [12]. Therefore, the effects of residual stresses are comparably the same as that of stress concentration. Residual stresses are now considered one of the leading factors influencing the properties of metallic materials. Thus, they should be given due consideration during the design and manufacturing of parts and components. Due to their self-equilibrating nature, the presence of residual stresses may not be readily evident, and so they may not be carefully considered during engineering design. However, they are stresses and must be given due consideration in the same way as stresses due to external loading. The hole-drilling technique based on ASTM E-837-13a standard [13] is used to measure the residual stresses, as presented in this paper; the residual stresses cannot be measured directly [14]. Usually, the elastic strains resulting from the relieved stresses initially present at hole position are measured directly, then, the residual stresses can be computed using mathematical relations.

To help engineers quickly generate innovative ideas to complete complex designs, many innovative methods have emerged. Commonly used innovative methods fall into two categories: intuitive methods and logical methods. Intuitive methods do not involve pre-analysis but produce innovative ideas by stimulating a dormant human thought process [2]. Because intuition is usually divergent, many detours generally occur. The logical method is based on the principles of science and engineering, and a large number of existing solutions must be analysed to systematically solve a problem. The theory of inventive problem solving (TRIZ) was proposed by Ahshuler, who analysed more than 2 million highlevel patents worldwide and proposed the involving invention, creation and technological innovation based on the principles of multiple disciplines [3]. Because TRIZ theory is highly abstract and can be repeatedly applied in different fields to solve different problems, it is now widely used as a scientific theory. Elevators, as vertical transport tools in buildings, can solve the problem of vertical passenger transport in high-rise buildings and have been increasingly widely used [4]. Elevators are indispensable in modern highrise buildings and serve users with high efficiency and quality. With the rapid development of the economy and the rapid growth of the urban population, the scale of modern buildings is expanding, and the span of buildings is increasing [5]. Traditional elevators can only solve the problem of vertical transportation. Passengers still need to spend time walking to their destination after leaving the elevator. Because an elevator cannot move horizontally, it restricts the connections between different elevators with different shafts. In 1996, the Otis Company first proposed the OdysseyTM elevator system, which uses transmission and traction drives in the vertical direction and a linear motor drive in the horizontal direction to achieve lateral elevator movement [6]. This system is mainly used to solve the transfer problems of elevators in different sections of high-rise buildings and can be applied to improve the mobility efficiency of passengers in large-span buildings.

It brings comfort and convenience to people, but it also brings new troubles such as nailing, leaking, and puncture [1] and [2]. According to the statistics from the transportation department of China, serious traffic accidents caused by tire leakage and bursting accounted for nearly 50 % of the total accidents, especially on expressways [3]. To solve the problem of tire inflation-free and safety, many research and production departments have been devoted to the study of safety tire technology and achieved many positive results [4] to [6]. Michelin launched an inflation-free radial tire called “Tweel”; it is a single unit that replaces the current inflatable tire assembly [7]. Narasimhan et al. [8] analysed the influence of material factors on the vertical stiffness and vibration characteristics of the Tweel during the rolling state. Ma et al. [9] studied the interaction between the Tweel and soil using the finite element (FE) method, and the established model can be utilized to analyse traction characteristics on a particular terrain. Kim and Kim [10] analysed the load-carrying properties and ground pressure of a nonpneumatic tire with a hexagonal honeycomb structure. In addition, the application of leak-proof technology and run-flat tires has also greatly improved the safety of vehicles. The mechanical elastic (ME) wheel investigated in the paper was a non-pneumatic safety tire with catenary structure, and it was developed to improve the mobility and safety of vehicles under harsh environment and driving conditions, such as rugged terrain and macadam pavement [11] and [12]. Since the ME wheel adopts a non-inflatable design, there is no danger of air leakage, puncture, etc. during the rolling process. Moreover, due to the use of a catenary structure, the ME wheel not only has the comfort and manoeuvrability of inflatable tires but also has the durability and damage resistance of airless tires. As the basis of the vehicle system dynamics, many difficulties exist in the study of tire-pavement interaction.

With the increasing demand for an environmentally friendly, non-flammable, readily available and hygienic fluid medium in hydraulic systems, water used as a pressure medium has caused renewed interest. However, the kinematic viscosities of water and mineral oil are 1 m2/s and 29 m2/s at room temperature at atmospheric pressure, respectively. Lower viscosity is accompanied by poorer lubricity and larger leakage. For certain matching clearances, the leakage rate of water is larger than that of oil, which will cause more internal and external leakages for water hydraulic systems [2]. Therefore, smaller clearances have to be considered in order to achieve reduced leakage. However, narrower gaps in water hydraulic components will cause mechanical wear [1] and [3] and fluid erosion [4] due to the poor lubrication of water, which will enlarge gaps, leading to more leakage [5]. Surface topography technology has emerged in recent years as an effective method to reduce energy dissipation [6] to [8]. Recent works on various forms and shapes of surface texturing for high efficiency [9] and [10], energy-saving [11] and [12] and long performance life [13] and [14] have been carried out, which has already succeeded in many industrial applications [8], [15] and [16], such as seals [17] and [18], bearings [19] and [20] and gears [21] and [22]. An attempt to optimize piston topography to minimize energy dissipation within the piston cylinder interface was made by Wondergem and Ivantysynova [23] and Ivantysynova [24], who proposed a barrel-like piston. Ivantysynova and Lasaar [25] demonstrated the potential of an advanced gap design using computer simulation. The load carrying ability, piston friction force and gap flow were computed for all investigated surface variations, and then an improved barrel-like piston was proposed to reduce energy dissipation generated by piston/cylinder assembly.
