摘　　要：本文重点介绍汽车用钢板弹簧的三维建模方法,基于CATIA软件草绘模块进行钢板弹簧中性层曲线的研究、绘制。在整车坐标下,根据钢板弹簧运动原则验证其垂直跳动运动轨迹、纵扭变形轨迹。本文所提出的建模在CATIA软件中易于操作,提高变载荷下的钢板弹簧匹配、建模的效率。CATIA绘制整车坐标下的钢板弹簧曲线直接、精准,且为后续平台开发提供有力的技术支持。This article focuses on automotive leaf spring 3D modeling method, studying and drawing leaf spring neutral layer curves based on CATIA sketch modules. In the vehicle coordinates, according to the principles of the leaf spring＇s vertical jump trajectory, longitudinal twisting deformation trajectory.The method of modeling mentioned in CATIA is easy to operate, raise the efficiency of variable load leaf spring＇s matching and modeling. CATIA drawing leaf spring＇s sport curve under the vehicle coordinate direct, accurate and provide strong technical support for the follow-up platform.
