Dynamic analysis of a machine model with time-varying mass. (English) Zbl 0861.70013
Summary: 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 allows to study the influence of the 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 programs that generate and solve these 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.
