Engine power turbine rotor balance test device and method

The invention discloses an engine power turbine rotor balance test device and method, and the device comprises a positioning body, a fixing part, a positioning ring, and a clamping part. The positioning body is connected with a bearing seat of a power turbine rotor; one end of the fixing piece is connected with the positioning piece, the other end of the fixing piece is connected with the positioning ring, and a mounting cavity for accommodating the power turbine rotor bearing seat is formed in the fixing piece; the multiple clamping pieces are arranged in the circumferential direction of the positioning ring at intervals, the positions of the clamping pieces are matched with positioning convex lugs on the rear end face of the power turbine rotor guider, and the clamping pieces are matched with the positioning ring to clamp the turbine rotor guider. The high-speed balance test device has the effect of improving the high-speed balance test efficiency of the power turbine rotor. 本申请公开了一种发动机动力涡轮转子平衡试验装置及方法，其中发动机
