摘　　要：为了解决回转机械能量和测量信号传输的难题,利用环形泄漏缝隙天线阵对声表面波传感器施加激励并传输测量信号,实现了旋转体上信号的无线无源持续检测。实现了回转机械扭矩非接触测量,为转轴动力监测智能化、自动化奠定了基础。For solving the energy and measurement signal transmission problem of rotary machine. The circled leaking aperture antenna was used to propel the SAW sensor and transmit the measuring signal. Wireless passive continuous detection of signal on revolving solid was realized. Non-contact measurement of rotary machine is realized. It provides a foundation for rotating shaft dynamics monitoring intelligence and automatization.
