Abstract

Abstract

Finite element analysis of engine valve mechanism is very necessary in modern mechanical design as an important support for basic experiment. Aiming at the optimal design of the performance for in-line four-cylinder diesel valve mechanism, the key thermodynamic and dynamic parameters of diesel engine were calculated and determined systematically. Firstly, the dynamic model of valve mechanism was established by using multi-body dynamic method, the finite element analysis results of static stress were calculated, and the module parameters in the dynamics model of parts were obtained. Then, Sharp 3D software was used to analyze the dynamics of the valve mechanism, and the camshaft strength of the valve mechanism was analyzed and optimized based on the analysis parameters. Finally, the main parts of the mechanism were analyzed through the finite element analysis function. The results show that the analysis results of the dynamics model of the valve mechanism are reliable, which are beneficial to the improvement and optimization of the dynamics design and performance parameters for the diesel engine valve mechanism.
