Why does the vibration exceed 100 after the turbine reaches critical speed?
Thread Content
For Hangqi T5793, there is abnormal vibration in the rear axle, with frequent high-level vibrations. When the vehicle is in motion, the vibration level on the rear axle is around 72, while the front axle shows normal vibration levels. Once the speed exceeds a certain threshold, the vibration level rises above 100. Please analyze the causes and suggest solutions.
The device indicates carbon buildup in the radial rear area, but I’m not quite sure about this issue after breaking criticality
Take the rotor out for high-speed balancing.

What’s the air seal clearance on the rear axle? Could it be that the axle is too close to the air seal?
