| description | The utility model discloses a vibration displacement measurement precision verification device for a blade tip timing vibration measurement system. The vibration displacement measurement precision verification device comprises a sensor to be measured, a reference sensor, a rotating speed synchronization sensor, a blade tip timing signal processing system, an angle adjusting device, a sensor clamp to be measured, a reference sensor clamp, a rotating speed synchronization sensor clamp, a rotary table, a positioning device and a fixed platform, the angle adjusting device and the rotary table are fixedly installed on the fixed platform, the relative position of the angle adjusting device and the rotary table is determined through the positioning device, and the angle adjusting device and the rotary table are coaxial. The probe end face of the to-be-tested sensor is opposite to the blade end face of the turntable upper blade disc; a probe end face of the reference sensor directly faces a blade end face of the turn |
