1.5MW风电齿轮箱实验分析与仿真应用
|
摘要
参照某1. 5MW大型风电齿轮箱的实验工况,基于ADAMS平台,在考虑齿轮内外部动态激励的情况下进行仿真。经过相关参数的调试,发现支撑刚体的阻尼系数对仿真结果影响很大,在其为0. 1的情况下,测点MP1处的仿真结果与实验数据在时域中的幅值误差能控制于19. 3%以内、在功率谱中的主要频率分布大致相同,这表明调参后的仿真模型具有一定的准确性。而后,在仿真模型中植入断齿故障,将测点处的振动信号进行时域特征与Hilbert解调的综合分析,结果与理论描述一致,进一步验证模型的精确性,同时也体现出此仿真模型与仿真方法对风电齿轮箱的振动特性与故障信号的研究具有一定的作用。
Referring to the experimental conditions of a 1.5 MW wind turbine gearbox,the simulation iscarried out considering the inside and outside dynamic excitation based on the ADAMS platform. Through thedebugging of relevant parameters,it is found that the damping coefficient of the supporting rigid body has greatinfluence on the simulation results. In the case of 0.1,the amplitude error of the simulation results and the experimental data at the test point MP1 in the time domain can be controlled within 19.3%,and the main frequency distribution in the power spectrum is much the same. It shows the simulation model after tuning parametercan be exact. Then,the broken tooth fault is implanted in the simulation model and the vibration signals at themeasured point are analyzed synthetically in time domain characteristics and Hilbert demodulation. The resultsare consistent with the theoretic description,which further verify the accuracy of the model. At the same time,it can also be proved that the simulation model and method can play a certain role in the research of vibrationcharacteristics and fault signals of wind turbine gearbox.
