| 摘 要： | 应用拉格朗日方程,得到了柴油机轴系受简谐力作用的非线性振动微分方程。根据非线性振动的多尺度解法,求得系统满足1/3次亚谐共振情况的一次近似解,并对其进行数值计算。给出了1/3次亚谐共振存在区域,并分析外激励、调谐值、阻尼等对系统的影响。最后建立Simulink模型进行仿真分析。

| Abstract: | The nonlinear vibration differential equation of diesel shafting subject to harmonic moment is established by means of Lagrange equation.According to the method of multiple scales for the nonlinear vibration the first approximate solution of 1/3 subharmonic resonance of the system is obtained.The area where 1/3 subharmonic resonance exists is given,numerical analysis of the influences of the excitation,dunting parameter and damping on the system are given too.At last,the simulation analysis is made by means... |
