| 摘 要： | 为了实现铝合金车门的轻量化,对铝合金车门的零件进行了尺寸优化.文章以某车型为研究对象,以铝合金车门质量最小为优化目标,扭转刚度和1阶模态频率为约束条件,车门零件的厚度为设计变量,运用HyperStudy的响应面法对铝合金车门的性能进行最小二乘法拟合,最后对车门的零件厚度进行了尺寸优化.经过迭代计算后,铝合金车门的零件厚度得到了优化.虽然车门的扭转刚度和1阶模态略有下降,但铝合金车门质量减少0.43 kg,轻量化效果明显.

| Abstract: | The purpose of this paper is to minimize the mass of aluminum alloy door. The torsional stiffness and 1st order modal frequency is used as constraint criteria, the thickness of door part is used as design variant, the performance of aluminum alloy door is optimized using HyperStudy and finally the dimension of door is optimized. The weight of aluminum alloy door still reduced 0.43 kg though the value of torsional stiffness and 1st order modal declined slightly. |
