| 摘 要： | 本文以液压马达作为研究对象，对其起动摩擦特性进行了测试与分析。实时获得了驱动扭矩、被测马达转角的变化过程。通过建模分析，准确估计出了起动时动、静摩擦特性的变化规律。得出了液压马达在起动的瞬间不存在摩擦力瞬态突变的结论，并据此对摩擦振动的产生机理加以分析，推导了产生爬行的各种临界条件。

| Abstract: | This paper introduces the frictional characteristics of a motor by testing the startup motion and the superlow speed running.Deducing the system's model,the thesis presents the states estimation of the dynamicstatic frictional torque,and gets a conclusion that a friction break does not occur.Basing this idea,the paper derives the kinematic equations of driven mechanism during the startup motion and gets the critical conditions of the frictional vibration and the frictional mechanism. |
