针对目前煤矿井下轨道牵引机车制动系统存在的反应时间慢、空程距离长、制动能力差等问题,提出了一种空间凸轮连杆机构结合鼓式制动器的机械式制动方案建立虚拟样机的方法,分析了空载和满载2种工况下制动系统的制动性能,得出制动过程中作用力、制动力矩等动力学参数及反映制动性能的制动时间、制动距离等参数。对仿真结果进行分析,证明了提出的空间凸轮连杆机构结合制动器的模型仿真的正确性与可行性。
Aimed at the problems of slow reaction time, long distance between trains and poor braking capacity of the braking system of underground locomotive traction locomotive, a virtual prototype is proposed based on the mechanical braking scheme of spatial cam linkage with drum brakes The braking performance of the braking system under no-load and full-load conditions is analyzed. The dynamic parameters such as acting force and braking torque during braking are obtained, and the braking time, brake time, Distance and other parameters. The simulation results are analyzed, which proves the correctness and feasibility of the model simulation of space cam linkage with brake.
