Abstract: Aiming at the problem of abnormal vibration of an ambulance during high-speed driving, the authors finally determine the cause of formation is that the engine did not assemble the dual-mass flywheel ac-cording to the requirement by subjective feeling and data collection, analysis, and troubleshooting. The problem is solved by improving the structure.
Key words: ambulance; transmission system; abnormal vibration; dual-mass flywheel
