摘　　要：针对掘进机无线遥控器研究着重于设备功能实现而人机合逸性考虑欠缺的问题,提出基于人机工程学理论的掘进机无线遥控器改良设计,在实现功能的基础上以人机系统为基础考虑设计问题,使人-掘进机无线遥控器-井下环境之间的相互关系达到最优,满足用户心理和生理需求。利用ABAQUS有限元分析软件对模型进行多姿态跌落的显示动力学仿真分析,确保遥控器外壳的结构强度符合设计要求。结果表明:模拟操作掘进机遥控器的姿态总体分值为95.8%,颈部、上臂、前臂以及双手的评价分值均在90%以上;70°角跌落是遥控器模型发生跌落冲击最危险角度,但其最大应力84.63 MPa小于材料的屈服强度,结构强度合理。Efforts on wireless remote controller design for the roadheader are mainly focused on realizing the function and rarely considers the aspect of man-machine integration.In this paper,an improved design based on ergonomics for the wireless remote controller of a roadheader is proposed.On the basis of realizing functions,this design considers the man-machine system when optimizing the relation among the man,the wireless remote controller and the underground environment,and meeting the psychological and physiological needs for the users.Using ABAQUS finite element analysis software,the remote controller is subjected to multi-posture drop explicit dynamics simulation analysis to ensure that the structural strength of the remote controller shell meets the design requirements.The results showed that the overall score of the simulated operation of the wireless remote controller was 95.8%,while all the evaluation scores of the neck,upper arm,forearm and hands were above 90%.The most dangerous drop impact angle of the controller model was 70°,and the maximum stress was 84.63 MPa,which is less than the yield strength of the material.Hence,the structural strength is reasonable.
