Cracks on the prestressed concrete sleepers are mainly caused by impact loadings form wheel and rail interactions. Thus, the excessive railway track maintenance cost. The effect and optimization of different prestressed sleeper shape under static and impact loadings has not been previously well investigated. Therefore, this paper focused on the optimization of prestressed concrete sleepers (PCS) shape looking at sleeper safety and sleeper volume. ANSYS 16 was used to analyze the static and impact loading on sleepers. The concrete part of the sleeper was modelled using a three-dimensional solid element, SOLID65 and the pre-stressing wires by truss elements, LINK180, to withstand the initial strain attributed to pre-stressing forces. This paper revealed that irregular hexagon sleeper shape with different width at rail seat and center section having 251 mm and 175 mm center width and height respectively; 281 mm and 200 mm end and rail seat width and height respectively is safe. This paper; thus, point out to irregular hexagonal shape sleeper are more economical and safe unlike the other modelled shapes.","PeriodicalId":234309,"journal":{"name":"Engineering Perspective","volume":"520 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123074384","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}

It is inevitable to use and spread of renewable energy sources to make energy production cleaner, more reliable and sustainable. In studies for this purpose, the use of fuel cell systems comes to the forefront thanks to its many advantages. The use of hybrid systems is becoming more common day by day in order to minimize the efficiency losses that may occur in the energy production, use and waste management process, to ensure energy reliability and to prevent systemic problems. In this study, hybrid systems created with fuel cells are discussed in detail, and examined under three main headings: hybrid systems created with renewable energy sources, created with storage devices, and created for energy recovery. It has been observed that the main purpose of hybrid systems created with renewable energy sources is to ensure energy reliability. In addition, the electrical energy required for the electrolysis of hydrogen used as fuel in fuel cells can be provided by photovoltaic panels or wind turbines, thus eliminating fuel storage and transportation problems. In hybrid systems created with storage devices, it is aimed to prevent instantaneous interruptions in the system by meeting the instantaneous power needed by the system and successful results have been achieved. In the hybrid systems created for energy recovery, it has been seen that it is possible to recover the heat and unburned fuel energy released from the fuel cell with thermophotovoltaic cells, gas turbines and heat exchangers.","PeriodicalId":234309,"journal":{"name":"Engineering Perspective","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125056598","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}
