摘　　要：提出了基于虚拟样机的无返回力矩钟表机构动摩擦系数确定方法,介绍了ADAMS中转动副的摩擦计算模型,根据文献确定了动摩擦系数的范围为0.03～0.15,构建了无返回力矩钟表机构的2D/3D混合仿真模型,利用一维离散优化搜索中的二分查找思想进行仿真,得到了钟表机构的动摩擦系数为0.11.An innovative method of determining the kinetic friction coefficient based on the virtual prototype of runaway escapement was present. The friction calculation model of revolute joint in ADAMS was described in detail. According to the references and experiment, the range from 0.03 to 0.15 of the kinetic friction coefficient of runaway escapement was put forward. The 2D/3D mixed virtual prototype of the runaway escapement was constructed and the kinetic friction coefficient at 0.01 was found using the bisection search method.
