Vibration Behavior of Bonded Mirror Models inside a SLR Camera

Abstract

This research deals with rebound vibration behavior of mirror inside a SLR camera. The differences of the mirror vibration phenomena is tested by using the two-rectangular-metal-plates model, which is bonded by double-sided tape. This bonded mirror model is fixed by a bolt and a nut on the horizontal rotatable shaft. In collision experiment, the bonded mirror model swings down freely and rotates about a shaft. Vibration behavior of mirror models is measured by laser displacement meter. As a result, the variation of maximum rebound angles have relationship with stopper position and the bonded position of the double-sided tape. The rebound angle is suppressed by changing the bonded position of mirror model in particular. In the experiment condition which is measured lower rebound angle, the mirror part and the body part show at a different vibration behavior and generate the opposite force each other.
