基于多目标的内燃机气门弹簧优化设计分析

The optimum design Analysis of valve spring in Internal Combustion Engines Base on the multi-objective

综合运用机械优化理论的优化设计方法,通过分析内燃机气门弹簧优化设计的设计变量、目标函数和约束条件,建立起以内燃机气门弹簧的质量、高度及防共振性能为目标函数的多目标优化设计数学模型,对多目标优化设计方法进行了探讨,并给出了设计实例。算例结果表明该方法具有工程实用价值。

The mechanical optimal theory and optimum design method were managed synthetically, through analysised the designing variables,target functions and related constraints of valve spring in Internal Combustion Englnes,it set up the optimum design math model of multi - objective. The optimum design multiple of multi - objective was explore. The designing example was present, the result showed that method is the more engineering praetical.
