Abstract
For the purpose of the shock absorption, using an oil damper and rubber, the author studied the vibration absorbing system with hydraulic damper, and tried the applied calculation between the absorbing constant and shaking amplitude in the case of installed agricultural engine.
The lagging time necessary for relaxation is only short, but the effect of decrease of the vibration energy is very remarkable. In the case of using rubber together with the damper, it was found from the calculation that the more the weight on damping system increases the less the engine vibration becomes.
