摘　　要：针对片梭织机在采用扭轴式投梭方式时存在的冲击大、效率低、能耗高等问题,提出一种多级式电磁投梭原理。根据电磁投射理论,建立了电磁投梭引纬的基本方案及片梭的投射/制动模型。通过理论模型、实验验证及仿真分析,得出多级电磁投梭的效率优于机械式投梭的结论;为使片梭在高速引纬时保持运动稳定性,提出了片梭磁悬浮筘座阵列系统。建立了电磁投梭与悬浮筘座的理论模型,分析了片梭的速度、加速度及其电磁场耦合特性。同时进行了电磁驱动加速试验、ANSYS有限元分析,验证了电磁驱动投梭引纬的可行性,实现以电代机"零传动"片梭引纬模式。For projectile Loom,torsion bar weft insertion mechanism,exists problems like large impact,low efficiency,high energy consumption, etc. A multi-stage electromagnetic picking principle was proposed. According to the theory of electromagnetic projection,the basic scheme of wefting insertion project/braking and the weft insertion models were established. By the theoretical model,experimental tests and simulation analysis,the conclusion that multistage electromagnetic casting efficiency is better than that of the torsion bar mechanism is obtained; for the projectile motion stability in high speed,the projectile magnetic suspension sley array system was proposed. The theoretical model of electromagnetic casting and magnetic suspension sley was established,and the velocity,acceleration and electromagnetic field coupling characteristics of projectile were analyzed. The feasibility of the electromagnetic drive was verified by the electromagnetic driving accelerated test and ANSYS finite element analysis,and ″ zero transmission″ projectile wefting insertion mode was achieved.
