    针对传统平衡装置需要将回转体拆出检测的不便性，尝试根据跟踪滤波和相敏检测技术研究出可用于典型旋转体设备的现场动平衡测试装置，此装置主要包括信号处理模块、下位机、上位机模块。通过现场模拟实验，证明该装置在600～1800 r· min－1范围内，能直接对整机和机组进行动平衡检测，数据的误差均在允许的范围内，其不平衡量最大误差为0．347 g，相位最大误差不超过5°，并具有良好的测量精度和重复性。

    This paper studies the test experimental device of the field balance of typical rotating equipment , in-troduces the use of filtering and phase sensitive detection technique.Compared with the traditional dynamic balan-cing device, this device can take dynamic balance detection on the machine and unit motivated directly without dis-assembling rotary body.To make a correct and comprehensive assessment of the performance of the machine quickly, we improve the production efficiency through the field simulation experiment, which proves that the device has high accuracy and good repeatability in the range of 600~1 800 r· min-1 and can be a good field balance testing experi-mental device.
