摘　　要：如果一个企业希望自己的效率能更上一层楼,就必须采用"六西格玛设计(DFSS)"的方法。文章介绍了运用DFSS的理论方法进行乘用车门内饰板注塑侧撞吸能块设计的基本思路。通过IDDOV设计流程,运用QFD、TRIZ理论及DOE等多种六西格玛设计工具开发出适用于乘用车门内饰板的注塑侧撞吸能块。相比传统吸能块,在满足整车性能要求的基础上,侧撞反力值下降了0.63kN,零件单价下降了60%,表明DFSS是一整套强大的设计质量控制工具,应用在产品设计开发阶段能取得理想的效果。If an enterprise wants its operating efficiency to be higher, DFSS should be used. The paper expatiates how to apply the fundamental principles and methods of Six-Sigma design to develop new plastic-injected door trim side impact energy absorber of passenger vehicle. The IDDOV process and various Six-Sigma design methods are utilized to develop a new plastic-injected side impact energy absorber of passenger vehicle such as QFD, TRIZ theory and DOE, which can drastically decrease a piece cost 60%, reduce back force of side impact 0.63 kN when it meets the requirements of a complete vehicle performance compared with traditional energy absorber. It shows that DFSS presents important references for door trim engineering development, it has better effect in the phase of product development.
