摘要
针对某型无人平台梯形车架承载结构重量过大、功能单一等问题,提出基于拓扑优化理论的桁架式车架设计方案,借助ABAQUS有限元分析软件开展拓扑优化计算,得到多工况下的车架拓扑优化结构,结合工程经验与技术要求,完成无人平台桁架式车架设计,对比实现轻量化设计目的,通过车架结构的有限元静态特性分析验证方案的可行性。
According to the problems of heavy load and single function of trapezoidal frame of a certain type of unmanned platform,the paper firstly puts forward a design scheme of truss frame based on the theory of topological optimization.Secondly,it carries out topology optimization calculation with ABAQUS finite element analysis software,and obtains the optimized structure of frame under multi-working conditions.Thirdly,it completes the design scheme combining with engineering experience and technical requirements.Finally,it compares the truss frame design of an unmanned platform with the lightweight design,and verifies the feasibility of the scheme by the finite element static analysis of the frame structure.
