| 摘 要： | 为揭示惯性通道直接解耦盘式液阻悬置的动力学特性和减振机理,建立了线性和非线性集总参数模型,并利用试验方法对液室柔度、等效活塞面积、惯性通道和解耦盘的惯性系数和阻力系数进行了参数识别,同时采用有限元法辨识了橡胶主簧的动刚度.仿真分析揭示了直接解耦盘在液阻悬置中的作用,悬置在低、高频两种工况的动态特性曲线与试验结果吻合良好,该液阻悬置改善了已有结构的高频动态特性.

| Abstract: | A lumped parameter model was proposed for the analysis of dynamic behaviour of a passive hydraulic engine mount(PHEM) with incorporation of inertia track and direct-decoupler,which is characterized by effective and efficient vibration isolation behaviour in the range of both low and high frequencies.Most of the model parameters,including volume compliance of the decoupler chamber,effective piston(area,) fluid inertia and resistance of inertia track and decoupler are identified by experimental approach.Numerical predictions are obtained through a finite element method for the responses of dynamic stiffness of the nonlinear rubber spring.The experiments are made for the purpose of validation of the PHEM.It was shown by comparison of the numerical results with the experimental observations that the present PHEM achieves fairly good performance for the vehicle industry. |
