摘要： PROBLEM TO BE SOLVED: To provide a liquid sealed vibration damping device preventing cavitation from occurring when a vibration of high amplitude is inputted, while securing a high attenuation characteristic of a normal amplitude. SOLUTION: A diaphragm 30 comprises an annular part 33 made of metal material in an annular shape, and formed integrally with a flexible part 31 formed by a rubber-like elastic body in a film-like shape. When the vibration of high amplitude is inputted, an outer peripheral film part 31a is prevented from expanding (deforming) by rigidity of the annular part 33, and the expanded spring constant of the diaphragm 30 is increased. As a result, the cavitation is prevented from occurring. Since the annular part 33 itself is displaced together with a central film part 31c and the outer peripheral film part 31a in the vibration input area of the normal amplitude, the extended spring constant of the diaphragm 30 is reduced. As a result, liquid flow effect is effectively exerted, and the attenuation characteristic is fully secured. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：提供一种液体密封的减振装置，当确保高正常振幅的衰减特性时，能够防止在输入高振幅的振动时发生气蚀。解决方案：隔膜30包括由环形形状的金属材料制成的环形部分33，并与由胶状弹性体形成的柔性部分31整体形成。当输入高振幅的振动时，通过环状部33的刚性防止外周膜部31a膨胀（变形），并且隔膜30的膨胀弹簧常数增大。结果，防止发生气蚀。由于环状部33本身与正常振幅的振动输入区域中的中心膜部31c和外周膜部31a一起位移，因此膜片30的延伸弹簧常数减小。结果，有效地发挥液体流动效应，并且完全确保了衰减特性。版权所有（C）2009，JPO＆INPIT
