Dynamics Analysis of Model 150 Diesel Engine Piston

Diesel engine piston has complex force condition and adverse working environment, and its motion state has a significant influence on noise, vibration and power of diesel engine, thermal deformation of the piston and liner, deformation on preload condition should be considered in the dynamics analysis. Dynamics analysis of piston based on the theory of secondary motion has been done in this paper, structure has been evaluated, and it provides reference to the piston further optimization.
