采用UG建立采煤机搬运车车体模型和履带支架,导入RecurDyn的履带车辆子系统Track(HM)建立采煤机搬运车虚拟样机,对履带车辆在松散土路、坚实土路、水泥路面3种地面的原地转弯过程进行动力学仿真,得到采煤机搬运车各种路面下仿真的转矩,为采煤机搬运车转向性能的研究与设计提供一定的理论基础。 Uses UG to establish the shearer body model and crawler bracket, and introduces RecurDyn’s Track Vehicle HM (Track (HM)) to build a virtual prototype of shearer loader. The crawler vehicles are used on three types of loose ground, solid dirt road, cement road surface The dynamic simulation of the on-the-spot turning process is carried out, and the simulation torque under various road surface conditions of shearer’s truck is obtained, which provides a theoretical basis for the research and design of shearer’s steering performance.
