| 摘 要： | 为克服传统模型的缺陷，建立了无返回力矩钟表机构“自由一接触”动力学模型和在自由和接触两个阶段具有相同形式的动力学方程，结合Crossley公式对传冲过程进行了较精细的描述，并以M739为例进行了数值仿真，再现了“二次碰撞”现象，为无返回力矩钟表机构动态设计、故障分析提供了一种有效的数值仿真方法。

| Abstract: | In order to overcome the limitation of a traditional model, a ‘free-contact’ dynamic model of runaway escapement and the dynamic equations which have the same form during the ‘ free ’ state and the ‘ contact ’ state were established in tnis paper. With the help of the Crossley equation, contact between the pallet and escape wheel was precisely described. A simulation on the clock mechanism of M739 was made. The results rfeveal the phenomenon oi the second impact’ known experimentally. An effective digital simulation method was provided for the dynamic design and failure analysis of runaway escapement. |
