某SUV麦弗逊前悬架客观测试与ADAMS/Car悬架K&C特性符合性研究

Research on the Compliance between Objective Testing of the MacPherson Front Suspension of an SUV and ADAMS/Car Suspension K&C Characteristics

本文以某SUV麦弗逊前悬架为研究对象,通过三维逆向提取竞品车硬点数据,并基于ADAMS/Car建立前悬架模型,进行车轮同向跳动和异向跳动仿真试验,对悬架KC仿真分析结果和实车的客观测试结果的符合性进行研究,最后通过模型硬点优化使仿真分析结果与实车测试结果有了较高的符合性,为后续拓展车型操纵稳定性开发、动力学性能预测提供了可靠的理论依据,有利于减少整车试验,缩短前悬架的开发周期。

This article takes the MacPherson front suspension of a certain SUV as the research object,extracts hard point data of competing vehicles through 3D reverse engineering,and establishes a front suspension model based on ADAMS/Car,and the suspension is simulated by parallel and opposite travel of two wheels.The consistency between the suspension KC simulation analysis results and the objective test results of the actual vehicle is studied.Finally,through model hard point optimization,the simulation analysis results have high consistency with the actual vehicle test results,which is developed for the subsequent expansion of vehicle handling and stability The prediction of dynamic performance provides a reliable theoretical basis,which is conducive to reducing vehicle testing and shortening the development cycle of the front suspension。
