| 摘 要： | 在分析高速电主轴功率与负载转矩关系的基础上,提出了一种负载扭矩软测量的方法.采用电主轴定子电压、定子电流、空载电流和主轴转速作为辅助变量,建立了基于BP神经网络的负载扭矩软测量模型.以航空发动机离合器轴承试验台扭矩检测为例,对软测量模型进行了仿真研究.仿真结果表明,该方法能够满足一定精度要求,为解决高速电主轴拖动系统扭矩传感器昂贵和不易安装等问题,提供了一种解决方法.

| Abstract: | A method of soft-sensing is put forward after the relation between spindle's power and load torque is analysed.The soft-sensing model based on BP neural network is built up,using the spindle's stator-voltage,stator-current,no load current and spindle speed as secondary variables.With an example of aviation engine clutch bearing test-bed torque measurement,the simulation is done for the soft-sensing model.It is shown from the result that the proposed method can satisfy some given precision requirements.And a good method is provided to solve the difficulty of installing the valuable torque sensor. |
