Finite element analysis of cylinder stress and deformation of a small rotary engine

摘要

Compared with the traditional engine,the structure of rotary engine is compact,the power density is greatly reduced,the speed increases greatly,but its thermal load problem is more prominent.The finite element analysis software ABAQUS was used to simulate the stress and the axial deformation of the rotary engine cylinder.And then the influence of speed on cylinder stress was analysed.The results show that the area of the cylinder with large stress is located near the bolt hole of the cylinder,the stress and deformation of the cylinder increases with the increase of the engine speed.
