By the concept of equivalent elements, expression of the equivalent pseudo-mass matrix and the equivalent forces of the wheel load's work device are derived through the finite element method. Then, dynamical modeling equations are obtained based on the generalized dynamical equation. The solution of the equations is used to reduction of fourth-order Runge-Kutta methods. According to this method, the expression is concise, convenient and improvement for the efficiency of the modeling. The equations reflect the relationship between the various components of the movement, which can provide an effective way to dynamical modeling and analysis of wheel loader's work device.
