| Abstract: | This paper discussed the details of calculating the natural frequency and main vibration mode of rubber engine mount system. A Matlab program was made up and checked to be very useful. It is rapid to obtain the characteristics of engine mount system using the program. It gives the theory base of estimating engine mount system sympathetic vibration, as well as it is base of analyzing the system response. |
