采煤机摇臂传动系统的优化设计

Optimum Design of Rocker Drive System of Shearer

采煤机是用于井下落煤的机械设备,其工作时依靠摇臂上下摆动实现对不同高度煤炭的切割,在工作过程中摇臂不仅要频繁摆动,而且要承受截割机构在综采作业时的振动和冲击,因此摇臂是采煤机中极易发生损坏的一个部件,一旦摇臂出现故障,将严重影响煤矿井下的综采作业,给煤炭生产企业造成较大的经济损失。采用多目标分析理论对采煤机摇臂传动系统进行稳健性优化设计,提高了摇臂传动系统在工作时的稳健性,为优化摇臂传动系统结构,提升摇臂传动系统的可靠性提供了有效支撑。

Coal shearer is a mechanical equipment used for coal falling in underground mine. When it works, it cuts coal of different heights by swinging up and down the rocker arm. In the working process,the rocker arm not only swings frequently,but also bears the vibration and impact of the cutting mechanism in the fully mechanized mining operation. Therefore,the rocker arm is one of the most vulnerable damages in the shearer. Once the rocker arm fails,it will seriously affect the underground fully mechanized mining operation of coal mine and cause greater economic losses to coal production enterprises. Multi-objective analysis theory is used to optimize the robustness of the rocker drive system of shearer,the robustness of the rocker drive system in operation is improved,and effective support is provided for optimizing the structure of the rocker drive system and improving the reliability of the rocker drive system.
