Dynamic Analysis of Double Pendulum with Variable Mass and Initial Velocities

The article presents an analysis of the dynamics of the double mathematical and physical pendulum with variable mass for variables initial velocities of the lower member of the pendulum. In the present system under the influence of gravity, mass exchange occurs between the upper and the lower member of the pendulum. Different initial velocity was used to force traffic. It has been shown that the increase in mass of the lower member of the pendulum and the adopted parameters and initial conditions results in reducing the vibration amplitude.
