Vibration Behavior and Rebound Angle on the Collision of Mirror Models inside a SLR Camera (Measurement of Collision Behavior of Rotary Support Rectangular Plates)

摘要

This study deals with the rebound vibration characteristics of a SLR camera\u27s internal mirror model. The mechanism of the mirror rebound phenomena is considered by using six types of rectangle metal plate models. In the experiment, the behavior of vibration during the rebound phenomena is observed. The mirror models are supported with rotational axis at long axis of the model. The mirror models swing down freely from the horizontal plane and then hit with a stopper. Amount of rebound is measured by a laser displacement meter. The results indicate that the rebound amount depends on the stopper position. The vibration behavior after the collision varies by stopper position. The vibration after the collision depends on the deformation while in contact with the stopper at the time of collision. We observed that when the amount of rebound is small, there is a tendency that the vibration after the collision becomes large. © 2013 The Japan Society of Mechanical Engineers.
