Summary
In the paper discrete systems with a variable mass and unilateral constraints are considered. The assumed physical and mathematical model enables analysis of large displacements of bodies and also a change of the load mass on the behaviour of the whole structure. Nonlinear equations of motion are solved using numerical integration. The paper contains the testing of equation of motion and computer programmes that generate and solve equations of motion. A special checking function for systems with time varying mass based on energy power balance is introduced. The results of calculations are the proof of correctness of the algorithms that have been used.
