The process parameters, such as the cross-head speed of the machine, have a significant influence on the quality of the product. The impact of two essential parameters was investigated to minimize or eliminate the product's production defects, such as thinning, tearing, and scratching. The first one was the impact of using two types of lubricating oil (grease and wax), and the products were compared with the dry condition (without using a lubricating oil). The second is the impact of changing the cross-head speed of the machine from 5 to 15 mm/min. This work aims to determine the optimum operating condition that prevents any defect in the product. The results showed that using lubricating oil resulted in better product shape, and the wax is better than grease in eliminating product defects. In addition, the results showed that the lower machine speed is preferred for eliminating production defects, where the final product has no obvious thinning, tearing, or scratching. The final product shape was evaluated visually because eye observation is the only way to judge the product shape.","PeriodicalId":510187,"journal":{"name":"Journal of Applied Engineering Science","volume":"39 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141270068","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 study, the research object is the main box girder of the overhead crane. The research objective is to find the parameters to obtain a lighter structure, which reduces the market price of the crane. The article studies the method of calculating crane girders and sets up the optimization algorithm. The study will use the Taguchi method, and ANOVA analysis to evaluate the influence of box girder parameters. The girder weight, stress, local stability, static displacement, and vibration frequency are response values. Constraint conditions are evaluated by examining each factor with response value according to the orthogonal matrix L16. Analysis of the Signal to Noise ratio and ANOVA by Minitab software will select the optimal parameters that satisfy the constraints, the goal is to reduce the volume compared to the original design. The test results of the crane with a lifting capacity of 250 tons, an aperture of 31 m, the girder weight reduced by 24.33 %, while the stress increased by only 6.16 %. The new design ensures suitable local stability conditions by making better use of the material's capabilities. With the new parameters, the technical criteria are guaranteed.","PeriodicalId":510187,"journal":{"name":"Journal of Applied Engineering Science","volume":"2019 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140415832","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}

The amalgamation of these energy modalities holds the promise of heightened energy efficiency coupled with reduced maintenance expenditures. This investigation endeavors to synergize wind turbines with photovoltaic (PV) solar panels in a hybrid configuration, capitalizing on the turbulent effluent from the wind turbine system as a cooling medium for the solar PV panels. Further studies are needed regarding the Solar PV-Wind Turbine hybrid cooling system, as a system needs to be designed to optimize the direction of airflow from the turbine as a cooling medium for the solar PV panels without compromising the turbine's performance. Experimental-scale modeling is implemented in this study, introducing a flat winglet deflector configuration to refine and optimize the airflow dynamics traversing the turbine, directed towards enhancing the performance of the integrated solar PV-Wind Turbine hybrid system. The results showed that the installation of solar PV panels and the addition of a flat winglet deflector configuration could improve the performance of the turbine. The highest Cp and Ct values obtained were 0.18476 and 0.66404 with an increased value of 21.74% and 20.56% respectively. Using the Taguchi method, the most optimal configuration for Cp is obtained for installing a PV solar panel with a height of 10cm with AoA for installing a flat winglet deflector of 5°. In the ANOVA analysis conducted, it is known that AoA has an effect of up to 71.57%, while the panel height has an effect of 24.69% with an error percentage of 3.73%.","PeriodicalId":510187,"journal":{"name":"Journal of Applied Engineering Science","volume":"181 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140417968","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}

Many countries are now facing the problem of having to deal with deteriorated infrastructure due to a lack of maintenance budgeting. This paper presents the dominant parameter in an Operational and Maintenance (OM) dam to build a cost estimation model to maintain the service life of the dam. The method used to identify cost-triggering parameters is based on activity-based costing and dam performance assessments using a combination of the modified Andersen, International Commission of Large Dams (ICOLD), and Dam Commission. The parameter was collected from fourteen independent variables, namely: dam height, irrigation area, sedimentation volume, grass area, wood vegetation area, corrosion area, concrete area, daily worker, corrosion expert, concrete deterioration, hydromechanical, physical performance, operation performance, and safety performance. The results of the model indicate that height, wood vegetation area, concrete maintenance area, hydromechanical deterioration, and safety performance are variables that affect OM costs. The OM costs can be reduced if the safety performance variable increases. This condition implies that if the safety performance component consists of dam monitoring activities, periodic inspections, green belt maintenance, water quality maintenance, and public awareness, the OM costs will decrease by 10%.","PeriodicalId":510187,"journal":{"name":"Journal of Applied Engineering Science","volume":"39 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140425617","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}
