Abstract
Various typed impact and vibration isolation devices have been widely used to protect the objects particularly in the field of medical, biology, or any precision device industries. These devices are mainly composed of the spring, damper, and actuator. On the other hands, this paper proposes another new simpler method to insulate the impact disturbance by using principle of center of percussion (COP). In the Experiment, the pendulum typed hammer gave impulsive force to a horizontal one-link arm to measure the impact force reduction performance. When the position of the rotational axis of the one-link arm and the impact point satisfies the condition of COP, the effect of the impulsive force by the hammer is suppressed. However, the one-link arm is needed a rotational spring to prevent from free rotational motion. This paper discusses the performance of the impact force reduction dependent on the presence or absence of spring via the several simulations and the experiments.
