自动导引车骨架结构优化设计

针对目前自动导引车自重系数较大的问题,以等强度、轻量化为研究目标,提出了一种适用于自动导引车骨架结构的优化设计方法。在对车身骨架结构进行力学分析的基础上,利用数学规划得出载荷分配与车轮位置的关系,得到车身骨架拓扑优化问题的约束条件,基于变密度法与优化准则法推导并建立了一种适用于自动导引车骨架结构的多准则优化模型,利用优化软件进行求解。最后,利用有限元软件对建立的优化模型进行仿真分析。仿真结果表明,所提方法用于自动导引车车身骨架优化是可行的。... Full description

2With the objective of same intensity and lighter weight,an optimization design method was proposed to reduce self weight coefficient of AGV.On the basis of mechanics analysis on AGV frame structure,load position and wheel position were worked out with mathematical programming, which were important constraint conditions for AGV frame structure optimization.A kind of multi-criteria formulation was proposed for AGV frame structure based on variable density method and opti-mality criteria and calculated by finite element software.A 3D optimization model was constructed andanalyzed. The results show that the optimization method is effective and reasonable.
