采用虚拟样机技术,应用ADAMS软件建立履带车辆刚性牵引装置动态载荷虚拟测试虚拟样机模型,在虚拟试验环境下测量了软土路面的滚动阻力系数及刚性牵引装置的动态载荷情况。通过仿真结果与实际测量结果的对比,验证了刚性牵引装置动态载荷的虚拟测试是可行的,这为刚性牵引装置的强度设计提供了载荷边界条件。笔者以平地匀速转向、匀速上坡和平地起步3种工况为例,对牵引装置的动态载荷进行了虚拟测试,结果表明,起步阶段刚性牵引装置所受载荷最大,达到6t。
Using virtual prototyping technology, the virtual prototype model of dynamic load virtual test of rigid traction device of tracked vehicle was established by using ADAMS software. The rolling resistance coefficient of soft soil pavement and the dynamic load of rigid traction device were measured in the virtual test environment. By comparing the simulation results with the actual measurement results, it is verified that the virtual test of the dynamic load of the rigid traction device is feasible, which provides the load boundary conditions for the strength design of the rigid traction device. The author takes the three kinds of working conditions, such as uniform steering at flat speed and steady starting at a constant speed, for example. The dynamic load of the traction device is tested in a virtual way. The results show that the rigid traction device at the initial stage has the maximum load of 6t.
