摘　　要：悬架系统设计开发是底盘开发的重要环节,对于整车操控性能有至关重要的影响。本文以某A级车的大量K&C数据为基础,利用面向总成特性的整车动力学仿真软件CarSim分析悬架K&C特性变化对整车操控性能的影响,并运用试验统计学中的DOE试验设计方法计算各特性车辆操控性能指标的主效应,得到了悬架K&C特性影响整车操控性能的规律,在设定悬架性能目标时重点关注,为整车开发早期的结构选择和后续的结构设计提供了依据。The design of suspension system is a crucial part of chassis research and development, which has an important influence on vehicle handling. Based on a large amount of test data obtained in one A-class vehicle’s K＆C characteristics test, use CarSim parameterized simulation software analyse the suspension K＆C characteristics’ change influences vehicle handling, and applying the DOE experiment design, have been carried out respectively and parameter main effect analysis is made to the virtual test results, and the effect rule of the A class vehicle suspension parameter which affect vehicle handling are obtained, providing a basis for the structure selection in the early stage of platform development and subsequent structural design.
