| 摘 要： | 针对企业生产的某型汽车驱动桥壳强度高、自重大、可靠性没有把握的情况，开展基于可靠性优化设计的研究。研究了该桥壳板簧座附近关键部位优化的目标函数和设计变量，在静疲劳、静载荷、侧倾强度、紧急制动等条件的约束下，建立了完整的可靠性优化的数学模型，并通过Matlab优化工具箱实施了优化。根据优化结果指导企业对驱动桥壳开展轻量化的减重而没有影响桥壳的可靠性，收到了良好的效果，体现了优化过程的科学性与可行性。

| Abstract: | For the enterprise production of a certain type of automobile driving axle shells high strength, since big, reliability wasn't sure, carry out based on reliability and optimal design of research. Study the shell leaf-spring seat near key parts optimization target function and design variables, in static fatigue and static load, the cabin strength, emergency braking condition such as constraints, the establishment of a complete reliability optimization mathematical model of optimal toolbox of Matlab, and through the implementation of optimized. According to the optimization results guidance for driving axle shells develop enterprise lightweight weight loss without influence the reliability of the bridge housing, has received the good effect, which reflects the process of optimizing the scientific and feasible. |
