摘要
采用位移和速度三次方的数学模型描述滞后非线性阻尼力。用多尺度法及奇异性理论研究了多频激励滞后非线性汽车悬架发生主共振时的动力学行为。结果指出 ,非内共振时为一树枝形分岔 ,而内共振时的分岔要复杂得多。
In this paper, the hysteretic nonlinear damping force is modeled by a series of displacement and velocity The method of multiple scales and singularity theory are used to investigate the main resonance and bifurcation of a nonlinear vehicle suspension system with multi frequency excitations It is concluded that a pitch pork bifurcation exists in case of non internal resonance and the bifurcation is much more complicated in case of internal resonance
