2) Analysis on natural frequency

Analysis on natural frequency of the anti-vibration mounting device including

high-elastic coupling is carried out with utilizing Finite Element Method (FEM).

With this expert technique, design of anti-vibration system is applicable

practically eliminating harmful vibration in service speed zone.

At the same time, actual measurement of vibration affected by 3rd vibration

of 4-stroke inline six cylinder engine mounted on rubbers on the test bench.

Fig. 14 shows the result of both calculation and measurement.
