摘　　要：首先阐述了差速器的传动原理,然后利用ADAMS建立了差速器齿轮机构的虚拟样机模型,并对该机构进行了两种工况下的仿真分析,得到传动齿轮的转速特性曲线及受力曲线,并通过曲线分析了差速器的差速原理。分析受力曲线能为差速器齿轮的有限元分析提供依据,并为其动态优化及疲劳寿命预测提供指导。The principle of differential transmission is introduced at first, and then the virtual prototype model of the differential gear mechanism is established by using ADAMS. The simulation and analysis of its two different working conditions are earned out, and the speed characteristic curve and force curve are got, the principle of differential is analyzed by the curve. Analysis on the force curve can not only provide force condition for finite element analysis of the differential gear, but also supply guidance for dynamic optimization and fatigue life prediction.
