摘要
通过ANSYS对AGV小车建立三维模型,初步设计简化的底盘结构,对其进行静力学分析,得到底盘vonMises应力分布和变形的状况。在施加相同约束条件和载荷下,分别采用变密度法和水平集法对结构进行拓扑优化分析,以保留质量的30%为优化目标,得到底盘的拓扑结构模型。根据优化结果简化修复三维模型并以相同的约束条件进行静力学分析。结果表明,2个新模型结构都满足承载及刚度设计要求,实现AGV小车轻量化,减少材料消耗。
The three-dimensional model of the AGV was established by ANSYS, and the simplified chassis structure was preliminarily designed. The static analysis was carried out to get the von-Mises stress distribution and deformation state of the chassis. Under the same constraints and the same load, the variable density method and the level set method were used to analyze the structure topology optimization, and the topology model of the chassis was obtained with the retention mass of 30% as the optimization objective. According to the optimization results, the three-dimensional model was simplified and repaired, and the static analysis was carried out under the same constraint conditions. The results show that the two new model structures can meet the load and stiffness design requirements,realize the lightweight of AGV vehicle and reduce the material consumption.
