Tribological Study for a New Designed Axial Engine by using CAE

Abstract

Abstract In this thesis the concept of the axial engine was studied and a new design of the axial engine was proposed. The whole engine was modeled in computer aided design (CAD) software (SolidWork). The tribological problem of the main bearing (connecting rod bearing) which modeled previously was studied and all the calculations related to that bearing such as the load that can support and the pressure distribution through its lubricant film were modeled in CAE software (MATLAB). It was concluded that this unique engine configuration includes many properties such as high power to the weight ratio and the ability to be variable compression ratio engine and also from MATLAB calculations that the optimum piston diameter for this model is 6.2cm.
