| 摘 要： | 研究不同频率、振幅的路面激励下悬架橡胶连接件的变形量.在Bouc-Wen模型的基础上,修正并建立了橡胶连接件的动态模型,并在数学模型中添加了频率和振幅对动态模型的影响.将橡胶连接件的非线性迟滞回线动态模型引入到传统的线性振动系统中,以车身振动作为橡胶连接件的载荷激励及其变形量的时域响应.相同的路面激励振幅下,橡胶连接件的变形量振幅随着频率的增加而逐渐增大,其迟滞回线包围的面积随着频率的增加而逐渐增大,其吸收的能量也逐渐增大,对衰减高频段的振动具有积极的意义.

| Abstract: | Suspension rubber mount's deflection is studied when input signal's frequency and amplitude are in different state. The final dynamic model is based on Bouc-Wen classic model; frequences and amplitude factor are also imported into the dynamic math model. The mount hysteretic nonlinear model is added into the linear vibration system,and the mount deflection time response is able to be calculated by using the vibration of bodywork obtained by linear system as input power. In the situation of sine excitation o... |
