In order to detect over speed of a car, the governor is installed in the elevator. Therefore, when forced vibration by mischief of a passenger occurs, it is important to prevent emergency stop operation. As one method to achieve this, we proposed detecting system of car vibration by mischief of a passenger. This system must set a reasonable level for various elevators. Therefore we made a model to evaluate behavior of an elevator with force vibration by mischief of a passenger, and confirmed the effectives of model by comparison with experimental result.
