| 1. | When the parameters and resonant conditions are equal , nonlinear inductance can change the topology structure of response curves . changing the nonlinear resistance and the nonlinear inductance can control peak value of response curves . changing other parameters , amplitudes of response curves will change correspondingly , but the responses are different , one modal could be controlled by the other 2的情况下,改变了响应曲线的拓扑结构;无论是电阻非线性还是电感非线性,都会抑制两个模态的振动;改变系统参数,振幅和共振区的大小会发生相应的变化,但两个模态对参数变化的响应程度是不一样的,可以通过一个模态控制另一个模态。 |
