Abstract:
A spring supported tray for mitigating a dominant frequency imparted thereto is provided. The spring supported tray includes a tray including a topside and underside, and configured to support an object on the topside, and N springs supporting the tray, N being a positive integer. A first end of each of the N springs is disposed at the underside of the tray. A second end of each of the N springs is disposed so as to receive vibrational motion imparted to the second end of each of the N springs from a source of the vibrational motion, the vibrational motion having a dominant undesired frequency fdom. Each of the N springs has a spring constant k defined by the equation: k = f n 2 4 π 2 w Ng where w denotes the collective weight of the tray and the object, g denotes the force of gravity, and fn denotes a natural frequency of the spring supported tray supporting the object, wherein fn is a lower frequency than the dominant undesired frequency fdom.
