摘要
本文利用相关参数对齿轮传动系统的固有特性与相关激振频率的共振区进行分析。分析表明:系统的低阶固有频率主要表现为与转动频率振动区重叠,系统中的高阶固有频率主要表现为中间轴和高速轴轮系的啮频共振;当系统的固有频率在共振区时,将引起系统的共振,影响系统的正常运行,研究结果将为风电机组齿轮传动系统的设计提供可靠的依据。
The dynamic model of gear system is established by the lumped -parameter method . Analysis was conducted by using the correlation parameters to the inherent characteristics of the gear transmission system and the resonance region of the relevant excitation frequency . Analysis shows that the low order natural frequency of the system is mainly manifested in the overlap with the rotating frequency vibration area , the high order frequency in the system mainly for meshing frequency resonance intermediate and high speed shaft gear . When the natural frequency of the system is in the resonance zone , will caused the system resonance , affected the system＇s normal operation . The results of the study will provide reliable basis for the design of wind turbine gear transmission system .
