The influence of friction component buckling on the vibration characteristic of the wet clutch

Journal of Physics: Conference Series, 2020
Abstract The multi-disc wet clutch is widely used in high-power vehicles and large construction machinery due to its capacity for high torque transfer and compact efficiency. However, the early-stage failure such as the buckling of the friction disk is hard to detect since its external performance is not obvious, which can impair the ...
