摘　　要：为了指导在透平机械中应用在线主动平衡技术,进行了利用双平面主动平衡技术和单平面主动平衡技术解决转子振动问题的对比实验研究。实验结果表明,没有应用主动平衡技术时,转子一阶临界转速时的振动峰值为550μm;应用双平面主动平衡装置后,可以将振动峰值减小到40μm以下,降幅达到93%;利用单平面的主动平衡装置,可将振动峰值减小到100μm以下,降幅达到80%。应用双平面或单平面主动平衡技术,都可有效地控制转子同频振动。实验研究表明这种电磁式主动平衡系统具有良好的工程实用价值。In order to direct the application of the active balancing device on the turbomachinary, the contrast experiments between double planes and single plane active balancing are carded out on the test rig. The test results indicate that the rotor vibration response can be decreased from 550μm to 40μm below by using double planes active balancing devices The vibration response decreases approximately by 93%. The test results indicate that the vibration response of the bending rotor can be decreased from 550μm to less than 100μm by using the single plane active balancing device and the vibration response decreases by more than 80%. The synchronous vibration can be controlled effectively by using active balancing device. The test results indicate that the active balancing device has good practical value in practice.
