摘　　要：针对非直圆筒形多道次拉深制件,目前缺乏拉深次数和中间件较优构型较为完备的设计步骤和方法。这里提出根据多道次拉深变形规律及其工艺措施,建立中间件构型的几何关系式。通过构造一组符合几何关系式的中间件构型,最终采用数值模拟方法,结合搜索中间件较优构型的5个判据,可以成功确定多道次拉深次数和中间件较优构型;通过非直圆筒形的音壳多道次拉深制件,验证了拉深次数和中间件较优构型设计步骤和方法的有效性。针对中间件较优构型的不足,设计了更为优化的新构型,数值模拟结果表明,增厚分布面积大幅下降71.2%。At present,there is a lack of complete design steps and methods for drawing times and middleware with better configuration for multi-pass deep drawing parts with non-straight cylindrical shape.The geometric relation of middleware configuration is established according to the law of multi-pass deep drawing deformation and its technological measures.It can be successfully determined by constructing a set of middleware configurations conforming to the geometric relations for multi-pass deep drawing times and the optimal configuration of middleware.Finally,numerical simulation method is adopted to search for the five criteria of the optimal configuration of middleware.Its effectiveness has been verified for drawing times and middleware better configuration design steps and methods through the sound shell of a non-straight cylindrical multi-pass deep drawing parts.A more optimized new configuration is designed,aiming at the deficiency of the optimal configuration of middleware.The numerical simulation results show that the thickening distribution area decreases by 71.2%.
