In order to analyze movement process of a wheel loader working mechanism and to calculate the load and strength of the part, a multi-body system software MSC.ADAMS was applied to build a mechanism-hydraulics coupling system simulation model. The lift arm, lever and link were assumed to be flexible parts, while others were treated as rigid. ANSYS is used to compute the data describing behavior of the flexible component of the working mechanism. Simulation of hydraulics dynamics behavior was done using ADAMS/Hydraulics. The method has been implemented in an MSC.ADAMS model of the working mechanism wheel loader. A whole working cycle processes of the wheel loader were simulated and the results gave the whole movement processes of the working mechanism and the flexible part strength status successfully.
