摘　　要：针对多楔带轮旋压过程中成形质量较差和旋轮寿命较低的问题,以东安513型发动机多楔带轮为研究对象,基于Deform平台对冷轧钢板08Al多楔带轮成形过程进行数值仿真,通过筛选旋压工艺参数,确定设计变量,并分析主轴转速、旋轮进给速度和旋轮半径对毛坯等效应力、旋轮成形载荷的影响;基于Design-Expert软件对旋压过程的各设计变量以多目标遗传优化算法进行优化设计,并通过试验验证了有限元仿真的可靠性。经过优化后,成形后的带轮等效应力减少了39 MPa,旋轮所受成形载荷减小了10.64%。Aiming at the problems of poor forming quality and low life in the spinning process of multi-wedge pulley,Dong'an 513 engine multi-wedge pulley was taken as the research object.Based on the Deform platform,the forming process of cold rolled steel sheet 08Al multi-wedge pulley was numerically simulated.The spinning process parameters were selected to determine its design variables.The effects of spindle speed,feed speed and radius of the roller on the equivalent stress and forming load of the workpiece were ana⁃lyzed.Based on Design-Expert software,the design variables of spinning process were optimized by multi-objective genetic optimization algorithm,and the reliability of finite element simulation was verified through experiments.After optimization,the equivalent stress of the formed pulley is reduced by 39 MPa,and the forming load on the spinning wheel is reduced by 10.64%.
