摘要
针对分动器的传统优化过程繁琐等问题,为实现对分动器力学性能和轻量化的同步优化,有必要引入多学科设计优化(Multi-disciplinary Design Optimization,MDO)方法。文中通过引入MDO思想,建立了多学科优化数学模型,阐述了自适应模拟退火算法(Adaptive Simulated Annealing,ASA),并构建了MDO设计流程图。并将此套方法理念应用于某款分时分动器的优化设计,在ISIGHT软件中搭建的优化平台上集成UG,ABAQUS和计算器组件,并基于ASA算法进行迭代计算。计算结果显示完成了分动器轻量化和力学性能的同步优化,同时验证了将多学科设计优化方法应用于分动器优化设计的可行性。
Considering the complexity of traditional design process on transfer case, it is necessary to introduce multi-disciplinary design optimization（MDO） method to achieve the goal that synchronous optimization of transfer case mechanics performance and lightweight. The multidisciplinary optimization mathematical model is set up with the MDO method, adaptive simulated annealing（ASA） is expounded and draw MDO flow chart is established. The theory is used to design a time share transfer case, and UG,ABAQUS and calculator are integrated on the optimization platform which developed with ISIGHT, and the iteration computations is worked out based on ASA. The calculation results show that the synchronous optimization of transfer case mechanics performance and lightweight are achieved, and the feasibility of MDO method is applied to optimal design of transfer case is verified.
