文摘
- •
The CVBVS with cubic nonlinearity resting on the nonlinear foundation is presented.
- •
The equations are derived and discretized by Lagrange’s equation and Galerkin method.
- •
The effects of nonlinear support stiffness, mass ratio and etc. are investigated.
- •
The paths to periodic motion through quasi-periodic or chaotic motions are observed.
