Abstract: The kinetic model of starting and stopping processes is established to study on the dynamic design question of the large belt conveyor. The resistance action is comprehensively considered the belt is visco elastic and the take-up pull has two freedoms in the kinetic model. The relation between the stopping mode and the calculation mode is discussed. And a kind acceleration starting curve with trapezoid is put forward. Studying the multi-drive belt conveyor system, dynamic analysis algorithms of the control starting and the stopping process has established adopting the following up control method. Then the dynamic design software BCD.20 is developed. Simulation of the actual system proved the correctness of the algorithm and software mentioned above, control of starting mode, stress state appears and the different stopping modes produce the different belt tension distributions.
