| 摘 要： | 带式输送机随着输送长度和运行带速的增加,输送机的动态特性对输送机的安全运行影响变大,特别是启制动工况.基于ADAMS的带式输送机的动态模型,应用ADAMS软件对带式输送机制动阶段的动态特性进行分析,给出了不同停车时间的输送带加速度和动张力的变化曲线.分析表明:无论头部还是尾部,停车时间越短,动张力变化及动张力波动幅度越大,且最大张力和最大加速度不是发生在速度变化的拐点处,而有一个滞后时间.输送带弹性造成应力波传播的速度滞后.

| Abstract: | The belt conveyer's dynamic characteristics exerts a greater influence on the safe operation,specially on the opens and brake operating mode as a result of the increase in its transportation length and the belt movement speed.This paper introduces the method of establishing belt conveyer's dynamic model,based on the ADAMS,offers an analysis of the belt conveyer's break phase's dynamic characteristic using the ADAMS software and gives the change curve of conveyor belt retarded velocity and the moves tension ... |
