摘　　要：用DFSS的方法论,进行外饰材料自攻螺钉的扭矩试验,证明采用对比塑料自攻的最小攻入扭矩和滑牙扭矩差值的试验方法能有效论证设计稳健性。通过设计稳健性的改进和提升,满足各项老化、耐久性能,同时能有效解决滑牙问题。As the trend of light mass, more and more automotive exterior and interior design is using plastic component. Weather - meter, crack, self frequency issues to be solved. Using DFSS method with -tapping screw stripping issues are the high torque validation and research, the robustness of self - tapping screws into plastic component is related to the delta torque between minimum tapping and no stripping toque. Through the improvement of structure and material, it is validated effective to solve the stripping issue.
