摘要

摘要: 应用有限元方法对混凝土输送臂基座进行静强度分析和模态分析，得出其静强度和固有频率满足轻量化设计基本条件。采用密度拓扑优化方法，以单元材料密度为设计变量，以静强度和固有频率为设计约束，以体积最小化为设计目标，对混凝土输送臂基座进行轻量化设计，引入对称约束和最小成员控制约束，保证优化后的可制造性。结果表明：在满足静强度和固有频率约束的前提下，基座质量可减轻18.3 kg。

Abstract: Finite element method is applied to analyze the static strength and modal properties of a concrete pump base, the results show that the static strength and natural frequencies satisfied the preliminary conditions of lightweight design. Then the density topological optimization method is adopted to carried out the lightweight design of the concrete pump base by taking the material density of element as the design variable, taking the static strength and natural frequency as the design constraints, and taking the minimum volume as the design objective. At the same time, symmetric constraints and minimum member constraints are introduced to guarantee manufacturability after optimization. The results indicate that with the constraints of static strength and natural frequencies, the weight of the concrete pump base can be reduced by 18.3 kg.
