摘　　要：带式输送机系统可认为是弹簧-质量系统,系统启动加速度过大会使输送带产生较大的动张力,引起瞬间冲击力,对系统产生冲击和振动,从而缩短零部件使用寿命。从黏弹性动力学模型分析入手,研究带式输送机启动特性,通过比较异步电机软启动方案,提出分级变频启动技术,利用Matlab仿真软件,进行启动性能分析,为系统设计提供较好的技术方案。The belt conveyor system can be considered as a spring - mass system. Too large starting acceleration have a greater dynamic tension, instant impact is caused, the system is shocked and destroyed, component life is shortened. The viscoelasticity model is analyzed, Belt conveyor startup characteristics is studied. Comparison of a variety of soft-start program, classification variable frequency start techniques is proposed. Based on Matlab, starting performance is analyzed, better technical solutions is provided.
