In the process of recycling it is possible to obtain pure granulated rubber and forms contaminated with cotton fibres with a predominance of rubber grains or of cotton fabric. Rubber granulate in the contaminated form is characterized by sound-absorbing properties similar to those of the average-quality mineral wool and other fibrous materials. It can be used as the core of sound-absorbing panels in anti-noise protections. The research results can be used both in the design of acoustical protection as well as in the course of the recycling process of other waste products for obtaining materials with sound absorbing properties.","PeriodicalId":38333,"journal":{"name":"International Journal of Mechanics and Control","volume":"27 1","pages":"117"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73927514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Construction of such dampers suggests that their properties should be dependent on fluid temperature, current of the coil and the relative velocity of the rod, which all change during operation. Then, an inverse model used to work out the current based on the required damping force may not be adequate, and performance of the overall semi-active control system can be significantly degraded. MR damper reaches its operating temperature in a short period of time, and thus it should be modelled, and the obtained inverse model should reflect such state. However, it has been observed that the hysteric behavior of the MR damper significantly differs depending on the current. The paper presents results of such analysis and recommends using a set of simple models appropriate for different ranges of this parameter. During control the models should be switched to guarantee the best operating conditions. Experiments for this research have been performed using MTS system.","PeriodicalId":38333,"journal":{"name":"International Journal of Mechanics and Control","volume":"1 1","pages":"82"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83899958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, in many cases automobile manufacturers (in particular bus manufacturers) still do not take advantage of numerical de­sign techniques, basing instead on intuition and experience. In this paper hybrid modelling of an urban bus is presented. A hybrid bus model links different types of modelling that can be used to perform a wide range of virtual analyses of vehicle static and dynamic behaviour. The major objective of development and usage of a complex model is to reduce a time and cost of vehicle design process improving vehicle quality at the same time. The main advantage instead is a possibility to exploit a model for different performances of vehicle subsystems. A hybrid model representing real vehi­cle behaviour consists of three modelling techniques commonly used in automotive industry: multibody modelling, finite element modelling and multi- port (block) modelling. A full model has been developed via commercial software which ensures its availability among automotive engineers.","PeriodicalId":38333,"journal":{"name":"International Journal of Mechanics and Control","volume":"154 1","pages":"13"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86277785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work some experimental results are presented of the measurements of the absolute velocity, its components and turbulence of the air flow through the radial fan rotor operating in various configurations. As the main measuring tool a three-axial hot-wire anemometer (CTA) probe has been used. The anemometer cooperates with a specialized software prepared by the authors for the spatial analysis of the flow field considered. In particular, the distribution of the circumferential velocity components behind the impeller rim has been examined, which affects directly the fan efficiency. As a result of the flow analysis behind the rotor rim a relationship has been established between the degree of turbulence and the machine efficiency. On the basis of the changes in the averaged-in-time velocity field behind the rim, the outflow of air from the blade passage has been evaluated.","PeriodicalId":38333,"journal":{"name":"International Journal of Mechanics and Control","volume":"16 1","pages":"87"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73293682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They vary in their calorific value and are used to decrease the usage of gases whose calorific value is higher. Coke oven gas from the coking process and process gases from an electric furnace in a copper plant are examples of such gases. Composition and calorific value of coke oven gas depend on coking parameters as well as on the type and quality of coal. The most common process where the coke oven gas is used is the process of heating combustion air in a heat regenerator. The gases from the electric furnace (due to low calorific value) require post combustion at the beginning of their disposal process. The paper addresses mathematical modelling of a coke oven battery regenerator as well as mathematical modelling of post combustion and cooling the electric furnace process gases. The regenerator mathematical model was elaborated for the simplified geometry of a real object making the assumptions for the heat transfer equations. The post combustion and cooling processes of the electric furnace gases are modelled with the aid of the Ansys software. This software was used for both elaborate simplified geometry of the analysed object and carry out the simulations. Mathematical description of occurring processes includes in this case combustion, turbulence and heat transfer.","PeriodicalId":38333,"journal":{"name":"International Journal of Mechanics and Control","volume":"319 1","pages":"164"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85424087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
