标题： Dynamics of a Gear System with Faults in Meshing Stiffness

摘要： 齿轮箱动力学由周期性变化的刚度特征。 在实际齿轮系统中，还存在一个间隙，可能导致齿之间的接触丢失。 由于这种接触的丢失，齿轮具有分段线性刚度特性，并且齿轮可以产生规则和混沌振动。 在本文中，我们研究齿形缺陷和不完善的影响。 使用非线性系统的标准方法，我们研究了啮合刚度存在各种故障的齿轮系统的动力学。 显示英文摘要

摘要： Gear box dynamics is characterised by a periodically changing stiffness. In real gear systems, a backlash also exists that can lead to a loss in contact between the teeth. Due to this loss of contact the gear has piecewise linear stiffness characteristics, and the gears can vibrate regularly and chaotically. In this paper we examine the effect of tooth shape imperfections and defects. Using standard methods for nonlinear systems we examine the dynamics of gear systems with various faults in meshing stiffness.
