摘要
阐述驱动桥试转和虚拟样机的体系结构,分为总体方案设计、子系统布局设计、样机建模、虚拟装配、样机运行仿真与分析评价等个子系统。研究各子系统的构成、功能和实现方法,并推导了飞轮转动惯量计算公式和气缸夹紧力的计算公式。结果表明,根据该虚拟样机技术开发的驱动桥运转试验机可以较真实地模拟驱动桥的工况,从而获得接近真实的驱动桥性能参数。
Virtual prototyping technology is introduced to the development of drive axle grinding test bench for single unit job lot production. The structure system of the virtual prototype, which includes scheme design, sub-system layout design, prototype modeling, virtual assembling, running simulation and performance evaluation, is put forward. The formation, function and realization of each sub-system are discussed. The formula of flywheel inertia and clamping force of gas cylinder are deduced. The results show that the test bench developed by this technology can simulate the real working conditions of drive axle to obtain its real performance parameters.
