AN ANALYSIS OF DAMPING TYPE INFLUENCE TO VIBRATION OF ELASTIC SYSTEMS
In this paper an analysis of influence of three type of damping on free vibration of elastic systems is presented. Linear viscous, nonlinear viscous and dry friction damping were considered. Special emphasis was on determining of critical damping value for all of three types of considered damping cases. Also, analysis of logarithmic decrement of amplitudes, evaluation and comparison logarithmic decrement for considered damping types is presented. For all types of damping, same features of system were used and then analysed. Since some of types of damping couldn’t be solved in closed form, numerical method was used. In this case, forth-order Runge-Kutta method is used for solving damping proportional to squared velocity of motion. Most important conclusion is that only system
