摘要

摘要: 履带架是履带行走装置的重要结构件,为了得到其在多个工况下最优结构形式,将拓扑优化的方法引入履带架的结构设计中。分析了履带架典型工况,建立履带架结构多刚度拓扑优化模型;采用带权重的折衷规划法将多目标问题转化成单一目标问题,基于多目标满意度理论提出动态权重系数的计算方法。该方法中权重系数是相应单目标值的函数,避免了主观设置权重系数造成的偏差。根据拓扑优化结果重构三维模型,对其进行静力分析,并与原结构模型分析结果对比,验证了本文优化设计的有效性。

Abstract: The crawler frame is working as a significant component for crawler travel unit. To obtain the optimal structure type satisfying the requirement of several loading conditions, three dimensional topological optimizations are introduced into the conceptual design of crawler frame. Both the mathematical model and the multi-stiffness topological optimization model of crawler frame are established by analyzing the typical loading conditions. To convert the multi-stiffness optimization problem into a single objective optimization, the weight compromise programming method is adopted, the calculation method of dynamic weight coefficient is proposed based on multi-objective satisfaction theory. Each weight coefficient is a nonlinear function of the corresponding single object, which can avoid the deviations of weight coefficient set by designers subjectively. Geometry model is reconstructed, followed by static analysis of the new structure. Compared with the analyzing results of the original structure, the results of optimized structure prove the validity of topological optimization of the crawler frame.
