基于CATIA的乘用车前驱动轴布置优化

Layout Optimization of Front Drive Shaft for Passenger Cars Based on CATIA

为研究乘用车驱动轴布置的相关设计方法,对布置方案的制定进行了分析。利用CATIA软件建立模型,在整车状态下对驱动轴总成进行运动仿真。通过验证驱动轴与周边零部件的位置关系,及时发现潜在设计风险。结果表明:驱动轴滑移摆角范围随布置状态改变,合理的布置角度及轴杆长度可以有效地控制滑移摆角的范围,进而在设计初期降低振动噪声及轴杆与周边零部件的干涉风险。

In order to study the relevant design methods for the drive shaft layout of passenger cars, the formulation of the layout scheme is analyzed. CATIA software is used to build a model to simulate the motion of the drive shaft assembly in the vehicle condition. By verifying the positional relationship between the drive shaft and the surrounding parts, potential design risk is detected in time. The results show that the range of sliding and swing angle of the drive shaft changes with the layout state. Reasonable layout angle and shaft length can effectively control the range of sliding and swing angle, thus reducing vibration noise and interference risk between shaft and surrounding parts at the early stage of design.
