摘要

利用传递矩阵方法分析直升机旋翼试验台传动系统振动特性。获得传动系统扭转振动模态及各阶模态振型、传动系统横向振动各阶固有频率及横向振动与试验台支撑刚度关系。实验测量旋翼试验台三向振动,旋翼转速经试验台共振区达960 r/min并稳定运行2~3 s后试验台振动发散,该回转频率对应横向振动一阶固有频率。经分析知振动发散与试验台主轴支撑刚度有关,并给出解决此类故障两种方法。

Abstract

Transfer Matrix Method(TMM) was used to analyze the vibration characteristics of the helicopter test rig. The torsional vibration natural frequencies and the modal shapes were obtained; Furthermore, each order natural frequency and the relationship between the lateral vibration and the supported stiffness of the test rig transmission were obtained. By experiment, three axial vibrations were measured. After the rotor ran over the resonance of the test rig to speed of 960rpm, the test rig would have been in steady run for about 2-3 seconds then the vibration went to diverge. That frequency of the spindle speed leading to vibration divergence was just right the 1st order natural frequency of the lateral vibration. Based on the vibration analysis, it was concluded that the vibration divergence was related to the supported stiffness of the transmission, and two methods on dealing with this malfunction were given.
