悬架KC试验分析

Analysis of Kinematics Compliance Test

汽车操纵稳定性被人们称为“高速车辆的生命线”,随着社会的发展,路面条件逐渐改善,汽车设计最高车速逐渐提高,操纵稳定性日益受到重视,称为汽车主要性能之一。悬架系统为操纵稳定性基础,为更加充分了解悬架系统基础性能,运动学特性和平顺性特性(KC)试验必不可少,运动学特性和平顺性特性试验测试能力的建立可以提升底盘开发能力,运动学特性和平顺性特性客观数据结合计算机辅助工程(CAE)仿真结果对比验证,可以提前发现底盘悬架缺陷及风险点,提高产品的整体性能。文章主要介绍KC试验过程、试验工况、试验曲线及曲线代表的含义,为后续操稳调校提供一定参考。

Vehicle handling stability is known as the"lifeline of high-speed vehicles".With the development of society,road conditions are gradually improved,the design of the highest vehicle speed is gradually increased,handling stability is increasingly paid attention to,known as one of the main performances of the vehicle.Suspension system as the foundation of steering stability,full understanding of suspension system for more performance,kinematics compliance test is necessary,the establishment of the kinematics compliance test ability can improve chassis development ability,kinematics compliance objective data combined with computer adied engineering(CAE)simulation results contrast test,can be found in advance chassis suspension defects and the risk point,improve the overall performance of the product.This paper mainly introduces the kinematics compliance test process,test conditions,test curve and the meaning of the curve representative,to provide a certain reference for the follow-up operation stability adjustment.
