摘要
合理设计车门内饰板形状和厚度可以有效地降低乘员损伤程度,同时减少内饰板质量。将隐式参数化技术运用在车门内饰板开发过程中,建立了参数化车门子系统有限元模型,利用多目标优化算法在近似模型基础上优化扶手形状和内饰板厚度。案例表明:该方法可以成功的解决车门内饰板安全性设计和轻量化要求的多目标问题,大大缩短开发周期。
The seriousness of injury and the mass of door trim can be reduced effectively by designing the shape of door trim reasonably. The implicit parametric technology was applied in progress of developing door trim and a parametric FE model of door subsystem was built. The shape of armrest and the thickness of door trim were optimized with multi-objective genetic algorithm in approximate model. The example indicated that the method can successfully solve the multi-objective problem about door trim's requirements in safety and lightweighting,and the development period was shortened greatly.
