摘要

摘要: 汽车的前轮定位参数包括前束角，外倾角，主销内倾角，主销后倾角等。主要以某车型为对象，借助三维偏差仿真软件VSA及机械系统动力学分析软件Adams，建立底盘前悬的偏差分析模型以及机构运动学模型，分析白车身、底盘前悬零部件的制造偏差对其转向轮定位参数的影响。通过分析零部件制造偏差对转向轮定位参数的影响关系，找出了主要影响因素，对合理优化关键零部件制造偏差，控制整车制造成本，提升整车性能具有很好的指导和实践意义。

Abstract: Four-wheel positioning parameters mainly include toe angle, camber angle, kingpin inclination angle and kingpin caster angle, etc. We chose a certain auto model as our analysis object, built the deviation analysis model and structural dynamics model of the front suspension with the help of three dimensional deviation analysis software called Teamcenter Visualization Mockup (VSA) and Automatic dynamic analysis of mechanical systems (Adams), trying to study the effect of auto parts manufacturing deviations to steering-wheel positioning parameters. The analysis results will help us find out the main influencing factors of the wheel positioning parameters, which has a good guidance and practical significance for the reasonable optimization of the key manufacturing deviations, which will bring the better control of the vehicle manufacturing cost and the improvement of vehicle performance.
