悬架运动特性的优化设计

Optimum Design of Suspension Movement Characteristics

为了有效提高汽车悬架运动特性参数的优化设计水平,介绍了悬架运动学和悬架运动特性优化方法的研究现状,由于悬架运动特性的优化是一个多因子、多目标优化问题,因此重点分析了能实现较好优化效果的3种主要方法。但通过对3种方法进行总结发现,对于多目标优化问题无论采用何种方法都只能做到在一定范围内提升悬架性能。对于悬架运动特性的优化设计,只有采用理论模型与精确的试验分析结合,才能获得更加优异的悬架性能。

This paper introduces the research status of the suspension kinematics and the suspension movement characteristics optimization method in order to improve Ihe optimum design of vehicle suspension movement characteristics, due to the motion characteristics of the suspension optimization is a multi-objective optimization issue, therefore analyzing three main ways to handle such problems is described in the paper. Through summarizing a variety of ways, no matter what the method is used, it can only improve suspension performance within a certain scope. Both using the theory of model and precise test analysis, it＇s a way lo get more excellent suspension performance.
