摘要
在已建立的考虑动态刚度、传递误差及齿侧间隙单对直齿轮传动系统动力学分析模型基础上,将齿侧间隙引起的刚度非线性函数按7次多项式拟合。运用多尺度方法分析了系统中存在的多种谐波共振频率因子,导出了系统在内部激励作用下主共振响应时稳态振动的频率响应方程,绘制了相应的频率响应曲线,并分析了系统中的静态载荷、动态载荷及阻尼对主共振响应的影响。
Based on the establishment of considering dynamic stiffness, transfering error and tooth backlash to the dynamic analysis of straight gear driving system, the stiffness non-linear function caused by the tooth backlash clearance is fitted in terms of 7th order polynomial function. The multi-scales approach is used to analyse the harmonic resonance frequency factors existing in the system; and the frequency-response equation of steady vibration of the primary resonance under the action of internal excitation in the system is deduced. The corresponding frequency-response curves are charted. The effects of static loading, dynamic loading and damping in the system upon the primary resonance in the system are analyzed.
