The invention belongs to the technical field of helicopter tests, and discloses a device and a method for measuring power loss of an intermediate speed reducer in a helicopter ground joint test. The device comprises a decoder, an upper computer, a tail inclined shaft torque acquisition assembly and a tail horizontal shaft torque acquisition assembly. The tail horizontal shaft torque acquisition assembly is mounted on a tail horizontal shaft, acquires the torque of the tail horizontal shaft through a strain gauge and transmits the torque of the tail horizontal shaft to the decoder, and the decoder decodes data and transmits the decoded data to the upper computer; the tail inclined shaft torque acquisition assembly is mounted on a tail inclined shaft, acquires the torque of the tail inclined shaft through a strain gauge and transmits the torque of the tail inclined shaft to the decoder, and the decoder decodes data and transmits the decoded data to the upper computer; and the upper computer calculates the torque and the rotating speed of the tail horizontal shaft and the tail inclined shaft under typical working conditions according to the decoded torque data of the tail horizontal shaft and the tail inclined shaft, and further calculates the power loss.

    本发明属于直升机试验技术领域,公开了一种直升机地面联合试验中间减速器功率损失测量装置及方法。装置包括:解码器、上位机、尾斜轴扭矩采集组件、尾水平轴扭矩采集组件;尾水平轴扭矩采集组件安装在尾水平轴上,通过应变片采集尾水平轴扭矩,并将尾水平轴扭矩传递至解码器,解码器将数据解码后传递至上位机;尾斜轴扭矩采集组件安装在尾斜轴上,通过应变片采集尾斜轴扭矩,并将尾斜轴扭矩传递至解码器,解码器将数据解码后传递至上位机;上位机根据解码后的尾水平轴和尾斜轴扭矩数据,计算尾水平轴和尾斜轴典型工况下的扭矩和转速,进而计算功率损失。
