摘要:
以商用车空气悬架C型梁为研究对象，采用材料替换并结合拓扑和尺寸优化的方法进行轻量化设计。基于变密度法，以结构刚度最大化为目标进行拓扑优化，获得结构初始构型。在拓扑优化结果的基础上，综合考虑3种工况，以板件厚度为设计变量，各工况下的应力和变形为约束条件，质量最小化为目标，进一步进行尺寸优化。优化结果表明，设计方案满足结构刚强度要求，降低了结构的质量，达到了轻量化的效果。
Abstract:
With the commercial vehicle’s air suspension C-beam as the research object, the material replacement was combined with topology and size optimization for lightweight design. Firstly, based on the variable density method, the topology optimization was carried out with the aim of maximizing the structural stiffness, and the initial configuration of the structure was obtained. Then, based on the results of topology optimization, considering three work conditions, further size optimization was conducted, which took the thicknesses of the plate as the design variable, the stress and deformation under each working condition as the constraints and the minimization of mass as the target. Optimization results show that the design not only satisfies the structural strength requirements, but also significantly reduces the mass of the structure and achieves a lightweight effect.
