Переменная масса элементов в виброударных системах: модели и численные результаты

Abstract

The variable element mass of weight in vibroimpact systems is wide spread phenomenon. When bodies masses are proportionate and amount of lost weight is essential, system parameters are changing significantly. It leads to the change of natural frequencies and sometimes to the change of oscillation character. This paper presents the task about influence of variable mass on the character on dynamical processes. Also are presented the comparison of displacements distributions in time for different mass change characters. Additional distributions describes displacements during one and several oscillation periods. The alignment for approach that put amount of lost weight in dependence of dissipative energy is given.
