Taking wheel loader as the research object, for the vibration problem under the driving condition of wheel loader, study an optimized differential connection loader driving stability system, model the whole vibration system of wheel loader with three degrees of freedom dynamics, and establish the mathematical model by using Lagrange's equation, combine with the stochastic engineering road excitation model under E-class road surface, and carry out the simulation analysis of the vibration system by MATLAB/Simulink module. Simulation analysis of the vibration system is carried out, and the results show that the body droop acceleration, body angular acceleration and work device angular acceleration under the driving condition of the wheel loader are significantly reduced after adding the driving stability system, and the three kinds of acceleration are further reduced after optimizing to the differential connection driving stability system, which indicates that the differential connection loader driving stability system further improves the driving smoothness of the loader.
