摘　　要：以带式输送机自动变频张紧装置为研究对象,利用AMEsim建立了其仿真模型,分析了启动过程中自动变频张紧装置的动态特性。研究结果表明,输送带的弹性模量提高1倍,张紧小车所提供的最大张紧力和位移就降低1倍,最大移动速度会降低1/3,提前15s达到移动速度峰值;启动时间越短,张紧小车受到的瞬时冲击载荷越大,因此启动时间不宜过短。The simulation model of the variable frequency automatic take-up of the belt conveyor was established by using AMEsim, and its dynamic characteristic during start-up process was analyzed. The results showed： if the elasticity modulus of the conveying belt doubled, the maximum tension and displacement of tensioning car became half, and the maximum moving speed reduced by 1/3, the speed peak time advanced by 15s; the start- up time shorter, the instantaneous impact load acting on the tensioning car the greater, so the start-up duration should not be too short.
