摘要
研究具有非线性的2自由度1/4汽车悬架模型在路面不平度激励下发生的混沌振动。对悬架模型在正弦激励下的混沌特性进行仿真分析。进一步通过建立2自由度1/4汽车悬架实验模型对系统的混沌特性进行实验分析,仿真和实验研究结果揭示系统发生混沌振动的可能性。
The present work investigates the chaotic vibration of the nonlinear quarter vehicle model with two degree-of-freedom through the excitations caused by rough road surface.The nonlinear dynamic property of vehicle model under the sinusoid excitations is explored through numerical simulations.Furthermore,the dynamic response in chaos field is analyzed by setting up the vehicle suspension experimental model.Both of numerical and experimental results confirm that chaotic vibration exists in the nonlinear quarter vehicle model with two degree-of-freedom.
