The graded material properties of FGM plate are modelled using layer-wise variation of material composition in thickness direction. The bending behavior of FGM plate is carried out using first order shear deformation theory with five degree of freedom. The mechanical properties of FGM plate are calculated using power law and Mori-Tanka Method. After validating the results of present formulation with the available results in literature parametric studies are conducted to assess the effects of material gradation, geometrical parameters like aspect ratio & slenderness ratio and boundary conditions on the bending behavior of FGM plate.","PeriodicalId":448218,"journal":{"name":"EngRN: Mechanical Systems (Topic)","volume":"209 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132867976","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 computer simulation of the processes in these engines is the key to reducing costs in the development of less polluting and more efficient combustion engines. The objective of the work is to model and control processes in the cylinder of the diesel engine. In the first part of the paper the detailed description of a mathematical model of a cylinder is given. This includes the description of cylinders thermodynamics, geometry, mass flows, combustion process and engine performance. Turbocharger modelling for the calculation of mean exhaust temperature and other parameters related to it also done. The second part is focused on MATLAB programing based on mathematical modelling. The results obtained by MATLAB simulation can be used to obtain some fairly good estimates of engine performance. These estimates are most useful for the understanding of basic engine performance. It also helps in assessing modifications as regards valve sizing, other geometrical parameters and various fuels.","PeriodicalId":448218,"journal":{"name":"EngRN: Mechanical Systems (Topic)","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122057504","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 analyzing the influence of a few parameters concerning gear efficiency.These parameters are:z1 - the number of teeth for the primary wheel of gear; z2 - the number of teeth of the secondary wheel of gear; alpha0 - the normal pressure angle on the divided circle; beta - the inclination angle. With the relations presented in this paper, it can synthesize the gear’s mechanisms. Today, the gears are present everywhere, in the mechanical’s world (In vehicle’s industries, in electronics and electro-technique equipments, in energetically industries, etc). Optimizing this mechanism (the gears mechanism), we can improve the functionality of the transmissions with gears. At the gear mechanisms an important problem is the interference of the teeth. To avoid the interference between teeth, we must know the minimum number of teeth of the driving wheel, in function of the pressure angle (normal on the pitch circle, alpha0), in function of the tooth inclination angle (beta), and in function of the transmission ratio (i).","PeriodicalId":448218,"journal":{"name":"EngRN: Mechanical Systems (Topic)","volume":"580 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134439557","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}
