车用旋钮的轨道设计、仿真分析与试验研究
|
摘要
旋钮轨道是影响旋钮手感的主要因素,精确的旋钮轨道设计能充分体现出旋转手感的效能。针对某车型后视镜旋钮,基于旋钮结构建立旋钮转矩数学模型,利用牛顿插值法将目标转矩进行离散求解瞬时角度的旋钮轨道半径;采用MATLAB对旋钮轨道半径求解过程进行编程,通过建立MATLAB与CATIA接口将运算结果输出至CATIA,实现轨道体的三维建模及旋钮装配;利用ADAMS对旋钮装配体进行动力学仿真分析获得转矩最大值和转矩挡位角及误差,完成对轨道体的转矩校核;开展旋钮实物的转矩测试试验并获取多组旋钮转矩实测曲线,实测结果验证了仿真分析及MATLAB程序设计的可行性与准确性。该方法极大地提高了车用旋钮轨道设计与造型的精度和效率。
Knob orbit is the main factor affecting the knob feel; the precise knob-orbit design fully reflects the performance of rotating. According to the structure of rear-view mirror knob, the mathematical model of knob torque is worked out, and the Newton interpolation method is applied to solve the orbit's instantaneous radius, with the operating torque as the target. Meanwhile, the radius-solving process is programmed by MATLAB which outputs the geometric curve of knob orbit; then, this curve is imported into CATIA, which realizes the three-dimensional modeling and knob assembly. The kinematic simulation analysis on the knob assembly is carried out with the aid of ADAMS, in order to obtain the maximum torque and the switch angle; then, the torque of orbit is calibrated. The experimental results show that both the simulation analysis and the MATLAB program design are feasible and accurate. This method greatly enhances the accuracy and efficiency of the knob orbit's design and modeling.
