摘要:
针对某机载显控台的轻量化设计问题，分析该显控台的承载特点，将下台体确定为轻量化设计的具体研究对象。采用结合了宽容分层序列方法的拓扑优化技术，确定了下台体的材料分布形式，基于该拓扑优化结果，利用还原设计方法构建了下台体的参数优化初始模型。在灵敏度分析的帮助下，有效减少了下台体参数优化时设计变量的个数，提高了参数优化效率。优化计算完成后，利用圆整的参数优化结果建立下台体的最终三维模型，该模型的理论质量较依赖经验设计的下台体减少了1.3 kg。轻量化设计后的显控台的随机振动仿真数据和试验结果，均证明该显控台的轻量化设计是成功的。
Abstract:
In this paper the problem of designing an airborne display console with light weight method was focused on. The characteristics of the console bearing the load were studied, with the half bottom of the console taken as the specific subject. The material distribution was determined with topological optimization technology integrated with forbearing stratified sequencing method. On the base of that, the prototype of the half bottom of the console used to parameter optimization was constructed. With the help of sensitivity analysis, some design variables were removed, so the optimization efficiency was increased prominently. As the optimization process finished, the half bottom of the console was modeled with the 3D software, which was about 1.3 kg lighter than that designed with experience. In the end it was proved that the work had achieved success by the random simulation data and random test.
