有限元素法在内燃机设计中的应用越来越广泛,已成为内燃机结构分析的有力工具。本文首先介绍了国外有限元素法在内燃机设计中的应用,其次介绍了国内有限元素法在内燃机设计中的应用状况。最后作者根据几年来的实践,对有限元素法在内燃机技术中的应用提出一些分析看法。 Finite element method is widely used in the design of internal combustion engine and has become a powerful tool for the structural analysis of internal combustion engine. This paper firstly introduces the application of foreign finite element method in the design of internal combustion engine, and then introduces the application of domestic finite element method in the design of internal combustion engine. Finally, according to the practice of the past few years, the author puts forward some analysis opinions on the application of the finite element method in the internal combustion engine technology.
