NONLINEAR OSCILLATIONS OF A BODY MOUNTED ON VISCOELASTIC OSCILLATING SUPPORTS
Keywords:
nonlinear oscillations, rigid body, vibration, Lagrange equations, viscoelastic support, degree of freedomAbstract
This paper examines the nonlinear oscillations of a rigid body mounted on viscoelastic supports. The equations of motion of the system are derived from Lagrange’s equations of the second kind for systems with a finite number of degrees of freedom. A solution method for the problem is developed, numerical results are obtained, and the influence of nonlinearity on displacement amplitudes is evaluated.
