摘　　要：为能给纯电动铲运机充电续能,提出了一种弓网续能充电系统。根据10 t级纯电动铲运机受电弓动力学特征及受电弓与巷道之间的工作条件设计了包括弓网各部件结构、弓头运动轨迹、升弓角及平衡杆转角等弓网续能系统参数。基于建立的受电弓动力学计算模型,结合多目标优化算法设计出纯电动铲运机专用受电弓,基于非线性有限元理论建立了纯电动铲运机弓网续能系统有限元模型,通过MARC软件对弓网续能系统受流情况进行了动态特性仿真和验证分析。结果表明:本弓网续能系统能在保证纯电动铲运机安全运行的前提下仅需12.5 s完成纯电动铲运机续能充电,提高了纯电动铲运机运行作业效率,具有很强的推广性。In order to recharge pure electric Load-Haul-Dump(LHD),a pantograph-catenary continuous energy charging system is proposed. The pantograph-catenary continuous energy system parameters,such as pantograph-catenary structure,bow head trajectory,bow angle and balance bar angle,are designed according to the pantograph dynamic characteristics and working conditions between pantograph and roadway. Based on the established pantograph dynamics calculation model,combined with the multiobjective optimization algorithm,the 10 t pure electric LHD pantograph is designed. Based on the nonlinear finite element theory,the finite element model of the pure pantograph-catenary system of LHD is established. The dynamic simulation and verification analysis of pantograph-catenary current were carried out through MARC software. The results show that the pantograph-catenary continuous system can complete the pure electric LHD continuous charge in only 12.5 s under the premise of ensuring the safe operation of the LHD,which improves the efficiency of LHD operation and can be widely generalized.
