The paper discusses the problem of dynamic loadings of the boom components in a front-end wheel loader during discharging of the bucket. A discrete two-dimensional model of a front-end loader on tyres was developed for numerical analyses of the loader boom dynamics. The mass of the entire machine including the mass of bulk material transported was reduced to three masses with five degrees of freedom (5-DOF). The masses are connected using the stiffness and damping elements. On the basis of this physical model, a mathematical model of the dynamic system was created. The final system of eight linear differential equations with time-dependent coefficients is solved using the Runge–Kutta method of the fourth-order. A computer program WYS1 that solves the mathematical model numerically was written using the ALGOL 1900 computer language. In addition, a simplified method is presented that can be used to calculate dynamic loadings of the boom system in front-end wheel loaders on tyres.
