DYNAMIC VIBRATION ABSORBER USING VISCOELASTIC MATERIAL AND CHARGED PARTICLE WIRE DEVICE USING DYNAMIC VIBRATION ABSORBER

摘要

PROBLEM TO BE SOLVED: To provide a dynamic vibration absorber using a viscoelastic material and a charged particle wire device using the dynamic vibration absorber which can appropriately adjust the natural frequency of vibration of the dynamic vibration absorber.;SOLUTION: The dynamic vibration absorber provided to a base plate 51 for vibration isolation is provided with the viscoelastic material 52 and a heavy weight 53 supported by the viscoelastic material 52. The viscoelastic material 52 is arranged in a predetermined position on the base plate 51, and the viscoelastic material 52 is a cluster of viscoelastic materials divided by a predetermined size. The dynamic vibration absorber is constituted so that the heavy weight 53 is placed on the viscoelastic material 52.;COPYRIGHT: (C)2009,JPO&INPIT
