基于ANSYSWorkbench的搬运机械手结构优化设计谢志江,孙玉,李诚,倪卫.(重庆大学机械传动国家重点实验室,重庆400030)StructuralOptimizationDesignofCarryingManipulatorBasedonANSYSWorkbenchXIEZhi—jl觚g·SUNYu·LICheng·NIWel(TheStateKeyLaboratoryofMechanicalTransmission.ChongqingUniversity.Chongqing400030,Chim)摘要:分别利用Pro/E和ANSYSWorkbench软件对搬运机械手进行三维实体建模与动静态特性分析,并通过形状优化分析设计对比了2种截面结构优化方案,确定使用空心方形截面结构
不仅提高了机械手的低阶固有频率,避免了共振的产生,还提高了机械手的刚度和强度,为结构的改进提供了可靠的参考依据
