最新的汽车零部件比过去的零部件更轻，提供更高的燃油效率和性能。本研究针对目前汽车设计的趋势，提出一种汽车悬架系统上控制臂的结构优化方法。上控制臂可采用先进的设计和材料技术设计成轻量型。本研究利用优化技术确定了上控制臂的形状。开发了铝合金Al 6061 M6作为钢的替代材料。强度性能是控制臂结构设计中最重要的设计要求，本文在优化过程中考虑了静强度。对上控制臂进行耐久性分析，预测其疲劳寿命，并采用Kriging插值法得到满足强度约束的最小重量。分别用ANSYS软件和EXCEL-Kriging软件进行了优化设计，并对两种设计程序的优化结果进行了比较。
Abstract The latest automotive components are lighter than their past counterparts, providing higher fuel efficiency and performance. Following the current trend in vehicle design, this study proposes a structural optimization method for the upper control arm of the vehicle's suspension system. The upper control arm can be designed to be lightweight with application of advanced design and material technology. In this research, the shape of the upper control arm was determined by optimization technology. The aluminium alloy Al6061M6 was developed as the steel-substitute material. Strength performance is the most important design requirement in the structural design of a control arm. In the optimization process of this study, the static strength was considered. Durability analysis was carried out to predict the fatigue life of the upper control arm. The kriging interpolation method was adopted to obtain the minimum weight that would satisfy the strength constraint. Optimum designs were obtained by ANSYS Workbench and the in-house program, EXCEL-Kriging, and the optimization results from both design programs were compared.
