摘　　要：针对现有磁阻式电磁投梭速度提升有限、效率低等问题,提出一种多级感应式电磁投梭方法。根据宽幅织机悬浮引纬的工艺要求,建立多级电磁投梭的理论模型,通过电磁力、动能计算和ANSYS仿真,分析引纬器形状、结构、电路系统续流支路、驱动线圈最佳触发位置对引纬器速度的影响,同时改变充电电压或驱动线圈级数以满足不同宽幅织机对引纬速度的要求。模拟三级感应式电磁投梭的加速效果,最高速度可达140.65 m/s,验证了多级感应式电磁投梭悬浮引纬方案的可行性。Aiming at the problems of limited speed improvement and low efficiency of the existing magnetoresistive electromagnetic shuttle,a multi-stage induction electromagnetic shuttle method is proposed.According to the technical requirements of suspended weft insertion for wide-width looms,a theoretical model of multi-stage electromagnetic shuttle is established.Through electromagnetic force,kinetic energy calculation and ANSYS simulation,the shape and structure of the weft inserter,the freewheeling branch of the circuit system and the optimal driving coil are analyzed.The influence of the trigger position on the speed of the weft inserter is analyzed.At the same time,the charging voltage or the number of driving coil stages are changed to meet the requirements of different wide looms on the weft insertion speed.Simulating the acceleration effect of the three-level induction electromagnetic pickup,the maximum speed can reach 140.65 m/s,which verifies the feasibility of the multi-level induction electromagnetic pickup suspension weft insertion scheme.
