In actual installation, rubber mount are usually excited by different engine force amplitude and frequency. For better characterization of rubber mount, dynamic properties of metal to rubber mount are tested in this paper by using hysteresis loop method. Stiffness and loss factor of rubber mount are calculated from measured hysteresis loop. Experimental works are carried to identify the non-linearity in the amplitude dependent and frequency dependent properties of rubber mount. the s-shaped of hysteresis loop represent as non-linear behavior of rubber mount. the comparison is done for the dynamic properties of rubber mount under different excitation condition. the non-linear behavior of the rubber mount under excitation forced are reported. the result show stiffness change non-linearly according to different amplitude excitation force under different excitation frequency. the observation is significant especially when the excitations force is higher than 5N for the small metal to the rubber mounts. However this observation is different compared to the condition where excitation frequency getting higher. the non-linearity in the rubber mount is becoming not significant when the excitation frequency is getting higher.
Key words: Rubber mount / Stiffness / Force amplitude and Non-linearity
