Abstract: In order to analyze movement process of the working device of multifunctional wheel loader and to calculate the load of every part, DenavitHartenberg method was applied to establish the kinematics of mechanism model, and simultaneously the dynamics model of hydraulic system was established. A multibody dynamics software MSC.ADAMS and its hydraulic module were applied to build mechanismhydraulics system simulation model. A whole working cycle process of the working device of wheel loader was simulated. The analysis results comprehensively show the movement process of the working device and the loaded condition of every part, and verify the mechanical properties of the working device and dynamic performance hydraulic system successfully.
