摘　　要：针对曲轴主轴颈加工切削振动和桁架机械手故障问题,设计了一种新型中心架体和托料装置。基于Simulation模块对SUC500DHT5双头数控车床托料结构进行拓扑优化设计,并根据拓扑优化结果进行校核。与初始托料架相比,优化后模型质量减小了31.86%、基频降低了6.64%,且优化后模型最大应力为1.214×10^(8) N/m^(2),仍符合强度要求。实验表明该新型中心架体结构稳定,适用于曲轴的自动化加工。托料装置在负载下使用安全系数满足要求,达到了拓扑优化目的。Designing a new type of steady rest and material rack devices to solve the vibration issue in crank axle of spindle neck lathe turning and gantry robot arm malfunction issue.Basing on Simulation module to topology optimization design in material rack structure which applying in SUC500DHT5 double head CNC lathe,according to the result to verify.Comparing with the original one,the new design weight decrease 31.86%,fundamental frequency decrease 6.64% and the maximum stress reach to 1.214×10^(8)N/m^(2) after topology optimization design,also meet the strength requirements.Experimental results show that the new steady rest structure is stable,fit the crank axle automatic processing.The material rack meets the factor of safety requirements under load applying situation,so the topology optimization design successed.
