The subject of this investigation is to analyze the oscillation of multi-plates immersed in a viscous fluid and the damping forces. The concept of multi-plates oscillating in a viscous fluid with the view of using the plates as a damper is believed to represent a new application. Conventional dampers consist of a cylinder filled with a fluid, usually oil, containing a piston which is free to move under the action of an external force. The velocity of the piston is regulated by the viscous resistance of the fluid flowing through the annular space between the piston and the cylinder walls, and the fluid is chosen so that this velocity will be small. The objective of this investigation is to develop a new model of viscous damper that operates on the principle of viscous damping with multiple parallel plates of negligible thickness moving relative to each other in a fluid medium. The plates can be flat or curved, such as concentric cylinders; however, the flat plates are analyzed in this investigation. The fluid contained between the plates and in the tank are prevented from leaking by provision of leak-proof bearings. Although the right end of the damper, part A, is shown stationary in Figure 3, it can be moveable as considered later. Figure 4 shows a sectional lateral view of the proposed damper. This figure suggests a method to hold the plates parallel during the course of the operation.
