Aiming at the problem of the system vibration stability of the multi-plate wet clutch on engagement process

according to the working principle and engaging characteristics of the multiplate wet clutch

the mathematical model of a wet clutch system engagement process is established

based on the complex eigenvalue and wet modal theory

by using numerical analysis and finite element method

the stability of multi-plate wet clutch engagement process is studied

and the influence law of multi-plate wet clutch key parameters on the system stability is studied.The results show that

through introducing the Jacobi matrix

the stability characteristics of the system can be calculated

the basis for subsequent wet clutch reliability optimization is provided.With the increase of the dual steel plate stiffness

the order number of unstable modes will increase

the stability of the system will fall.As the role of pressure increases gradually

each mode corresponds to the real value also increases

the stability of the system show a downward trend.
