对气门机构优化设计方法的探讨

The Optimum Design Method for Valve Train

本文讨论了内燃机气门机构优化设计的命题、优化目标及条件，指出了某些局部优化命题不能反映气门机构设计中实际可能存在的种种情况和相应不同的主要矛盾，以及某些优化目标和约束条件的不尽合理之处。本文提出了一个进行气门机构设计分析和总体优化的新思路。

The topics, optimum objects and constraints of valve train optimum design are discussed in this paper, and some design methods are pointed out to be incapable of representing the various situations and problems of valve train design. A more rational optimum design strategy for valve train is proposed, and a corresponding software is introduced.
