为了降低带式输送机的起动负荷，将电液比例控制技术施加于行星轮系，设计了一套新型的可控起动系统；针对该系统建立了数学分析模型，施加单位阶跃信号，研究其动态特性，分析了系统参数对动态特性的影响；对一设定加速度，计算了系统输出加速度的特性，研究结果表明，这种新型可控起动系统可控制起动加速度，且胶带的动态应力比液力耦合器－减速器的起动系统要低
In order to reduce the starting load of the belt conveyor, a new set of controllable starting system was designed by applying the electro-hydraulic proportional control technology to the planetary gear train. A mathematical analysis model was established for the system, and the unit step signal The dynamic characteristics of the system are analyzed. The influence of the system parameters on the dynamic characteristics is analyzed. The acceleration of the system is calculated and the output acceleration of the system is calculated. The results show that the new controllable starting system can control the starting acceleration and the dynamic stress ratio of the tape Power Coupler - Reducer starting system to be low
