中文摘要:为获得空间桁架结构的合理构型,以某空间设备支撑结构为例,分析结构材料在设计空间的分布形式和桁架结构的传力路径。在已知载荷约束和设计空间大小的条件下,基于连续体拓扑优化方法,以静态多工况刚度和动态固有频率为多目标函数进行优化分析。依据设计要求确定计算模型的结点数和结点位置,获得满足要求的空间桁架结构并进行优化设计。优化结果比原模型质量减少36.7%,一阶模态提高3.6%。

Optimization design of space truss structure
Abstract:In order to obtain the reasonable configuration of space truss structure, the distribution form of structural material and the transmission path of truss structure are analyzed by taking the supporting structure of space equipment as an example. On the basis of continuum topology optimization method, under the condition that the load constraint and design space size are known, the static multi-condition stiffness and dynamic natural frequency are optimized and analyzed as multi-objective functions. According to the design requirements, the node number and node positions of the calculation model are determined, the space truss structure is obtained, and the optimum design is achieved. The final optimization result is that the mass of the original model is reduced by 36.7% compared with the original models, and the first mode is improved by 3.6%.
