摘要
针对两自由度 1 /4汽车悬架模型 ,用多尺度法研究了具有位移和速度三次方项的滞后非线性汽车悬架在多频激励下的组合共振 ,并用奇异性理论进行了分析。最后 ,用数值方法分析了各系统参数对幅频曲线的影响。
The method of multiple scales and singularity theory are used to investigate the combination resonance and bifurcation of a nonlinear vehicle suspension system with multi-frequency excitations. The suspension system is simplified to a 2 DOF quarter-car model and the system equations of motion with the cubic of displacement and velocity are built. In addition, the influence of systems parameters on response curves is studied numerically.
