The mathematic model was a nonlinear oscillator driven by wave exciting force while the restoring force was exponential.
系泊运动的数学模型是一个具有指数回复力特性的非线性强迫振子,以波浪作用力为外激励。
The example shows that the bifurcation condition of single degree of freedom nonlinear oscillator can indicates the motional behavior of nonlinear flutter system.
