摘　　要：为了克服传统编码器测速方案安装不便、成本高等问题,对基于振动加速度的旋转机械瞬时转速估计方法进行了综述。主要总结了当前6种主流的瞬时转速估计算法的基本原理,并通过工业齿轮箱不同工况下的转速测试,对这6种测速方法进行比较评价,分析了它们的优缺点和适用范围。结果表明,振动加速度信号间接蕴含了齿轮箱的转速信息,能够用来较为准确地估计齿轮箱的瞬时转速,这对于服役工况下齿轮箱的状态监测与控制具有重要意义。In order to address the problems of installation inconvenience and high cost of traditional en⁃coder for speed measurement,the estimation method of instantaneous speed of rotating machinery based on vi⁃bration acceleration is studied and summarized.The present work recapitulates the basic principles of six popu⁃lar instantaneous speed estimation algorithms,investigates these six speed measurement methods through the speed test of industrial helical gearboxes under different working conditions,and analyzes their advantages and applicability.The results show that the vibration acceleration signal indirectly contains the speed information of the gearbox,which can be used to accurately estimate the instantaneous speed of the gearbox,and which is of great significance for the condition monitoring and control of the gearbox in operating conditions.
