Abstract

Hydraulic engine mounts are used to support powertrain and reducing transmitted vibration from motors to the frame. One important use of HYDRAULIC ENGINE MOUNTs is in the air industry. In turbofans, the maximum amplitude of vibration occurs at the two distinct frequencies. So, by using an engine mount with maximum flexibility at these frequencies (called NOTCH FREQUENCY), one can achieved reducing the transmission of the engine induced vibrations to the cabin. Here in this paper, using bond graph method, linear modeling of a double-notch HYDRAULIC ENGINE MOUNT is done. Then, by applying nonlinear terms, NONLINEAR MODELING of the engine mount is carried out using variance method. It has been shown that the DYNAMIC STIFFNESS will be changed by considering nonlinear terms. Finally, sensitivity analysis is applied to show the effect of each parameter on the dynamic behavior of the mount. It has been shown that the diameters of outer and inner inertia tracks are most effective parameters on the first and second notch frequencies, respectively.
