Example 2: Figure below shows the principle of a vibration damper. The main platform (mass mi) is suspended on a spring/damper system. The suspension has the spring conn Di and the friction coefficient RF. On the platform is a device that produces oscillatioss such as a vibrating sieve (indicated by the dashed box in Figure). The oscillabory force im- posed on the platform by the device can be described as Fit)-Fn(t) D. m. D2 The...
