| Abstract: | The high-horsepower flywheel is a component of a high-horsepower engine for commercial vehicles.During the operation of the flywheel,due to frequent friction with the clutch,there were problems in the after-sales market,such as clutch slipping,difficulty in starting and large vibration,etc.After disassembling,it was found that the surface of the flywheel appeared uneven wear and surface micro-cracks as the main failure mode. |
