| 摘 要： | 为分析某新型被动液阻悬置低频和高频的动态特性,建立了该悬置的集总参数线性模型,并利用键合图模型建立了线性和非线性状态方程,仿真特性曲线与试验结果基本吻合,表明所建立的液阻悬置模型能够较精确分析该悬置的动态特性.同以往悬置的动态特性相比,该悬置具有良好的频变幅变特性,拓宽了以往被动液阻悬置高频的使用频率,改善了悬置的动态特性.

| Abstract: | A lumped parameter model of a certain novel passive hydraulic engine mount (PHEM) was built in order to analyze the dynamic responses in high and low frequency.Linear and nonlinear mathematical state equations of bond graph model for the mount were developed.The experimental results show a good agreement between the estimated model and the test curves.The results provide a reasonable model by considering the dynamic response of the mount.The mount has good performance of frequency and amplitude dependent.It increases the range of work in high frequency and improves the dynamic responses compared with the old mounts . |
