摘要
针对某型双馈发电机在运行中出现的振动过大问题,基于ADAMS/Vibration振动分析模块建立了双馈发电机与弹性支撑动力学仿真模型,进行了固有频率、能量解耦与自功率频谱分析,确定了弹性支撑刚度对发电机振动的影响关系,提出优化弹性支撑刚度与阻尼参数进行减振的方法。在ADAMS/Vibration平台上对优化弹性支撑后的发电机振动状态进行仿真评价,并与实际振动测试情况进行对比。结果表明,仿真与实测情况基本一致。通过优化弹性支撑,该型双馈发电机振动值得到大幅降低。
Aiming at the excessive vibration of a DF generator during operation, a dynamic simulation model of DF generator and elastic support was established based on ADAMS / Vibration vibration analysis module. The natural frequency, energy decoupling and self-power spectrum were analyzed. The influence of the stiffness of the elastic support on the vibration of the generator was determined and the approach of optimizing the stiffness of the elastic support and damping parameters was proposed. The vibration state of the generator with optimized elastic support was simulated and evaluated on the ADAMS / Vibration platform and was compared with the actual vibration test. The simulation results are in substantial agreement with the experimental results. By optimizing the elastic support, the vibration of the DF generator is greatly reduced.
