基于RAMSIS的乘用车方向盘中心点研究

Research on the definition of steering wheel center point of passenger car based on RAMSIS

以某些车型的歇脚板、地毯和加速踏板为基础数据,针对不同坐姿高度的A类车型,采用RAMSIS软件自动摆放95%的中国人群,获得不同的方向盘中心点位置,以此为研究对象,推导出方向盘中心点相对座椅参考点(SgRP)的X和Z向位置与座椅高度(H30)的关系式,对方向盘中心点的位置确定提供了一种有效方式,为汽车总布置的假人摆放和逆向工程提供了有力的工具。

Based on the foot rest, carpet and accelerator pedal of a certain model, for A class models with different sitting heights, the RAMSIS software was used to automatically place 95% of the Chinese drivers, and different steering wheel center points were obtained, which was taken as the research object. The relationship between the X and Z directions of the steering wheel center point relative to the seat reference point (SgRP) and the seat height (H30) is derived, which provides an effective way to determine the position of the center point of the steering wheel and a powerful tool for dummy placement and reverse engineering of the general layout of the car.
