摘　　要：设计一种新的振动信号积分算法,实现对不同振动加速度传感器的标定,并验证了算法的可靠性。通过采集气波机运行工况下不同部位的振动信号,分析发现各测点振动的频率成分为喷嘴射流频率及其倍频。基于时间、均方根、峭度3个特征量进行气波机振动特性分析,结果表明,气波机整机振动是由喷嘴旋转射流导致的,振荡管U形管弯头处振动信号最为尖锐,研究成果可为后期振荡管抗振设计提供参考。A new vibration signal integration algorithm was designed to realize calibration of the different vibration acceleration sensors,including the verification of the algorithm reliability.Through collecting the vibration signals of different parts of the air wave refrigerator under operating conditions,the frequency component of the vibration of each measurement point can be divided into the frequency of the nozzle jet and its multiple frequency.Analyzing the vibration characteristics of the air wave refrigerator based on time,root mean square and kurtosis shows that,the rotating jet of the nozzle causes the vibration of the air wave refrigerator,and the vibration signal becomes the most sharp at the elbow of the U-shaped tube of the oscillation tube.The research results can provide reference for the anti-vibration design of the oscillation tube in the later stage.
