摘要

>For the existing roadheader, the transmission system of the cutting unit cannot regulate speed and the cutting motor may break down because of the impact vibration. In this study, the power reflux hydraulic transmission system, which is a new continuous variable transmission system, is put forward to ameliorate these problems. The basic characteristics such as the speed ratio, efficiency and torque ratio are analysed on the basis of expounding the basic structure and operational principle of the power reflux hydraulic transmission system. The dynamic model of the transmission system of the cutting unit is established. The pulse signal is used as the simulation of the loads, when the roadheader suddenly encounters the high strength rock. Then the torsional vibration characteristics of the existing roadheader and the roadheader that is equipped with the power reflux hydraulic transmission system are analysed. The contrastive simulation results show that the motor and transmission system vibration of the roadheader which is equipped with the power reflux hydraulic transmission system is markedly attenuated relative to the existing roadheader. So the power reflux hydraulic transmission system can protect the cutting unit's motor and the transmission system.

对于现有的道路主机,切割单元的传输系统不能调节速度,并且由于冲击振动,切割电机可能会破裂。在该研究中,提出了一种新的连续变速器系统的电力回流液压传动系统来改善这些问题。在阐述功率回流液压传动系统的基本结构和操作原理的基础上,分析了速比,效率和扭矩比的基本特性。建立了切割单元的传输系统的动态模型。脉冲信号用作负载的模拟,当陆路主机突然遇到高强度岩石时。然后,分析了现有的道路主机的扭转振动特性和配备有电力回流液压传动系统的道路主机。对比模拟结果表明,配备有电力回流液压传动系统的路标的电动机和传动系统振动相对于现有的道路主机显着减弱。因此功率回流液压传动系统可以保护切割单元的电机和传动系统。
