Title:
VIBRATION TESTER OF MULTI DEGREE OF FREEDOM
Document Type and Number:
Japanese Patent JP3152411
Kind Code:
B2
Abstract:
PURPOSE: To make the whole construction simple and small by a construction wherein a vibration table in the shape of a right-angled rectangular parallelopipedon is formed horizontally, dynamic electric vibration generators in directions X and Y are provided for a plurality of sets of vibrating means and the gravity of the vibration table is supported by a supporting means.
CONSTITUTION: The vibration tester is constructed of a vibration table 1 in the shape of a right-angled rectangular parallelopipedon formed horizontally, a plurality of sets of vibrating means having dynamic electric vibration generators 3-1 and 3-2 joined to one-side wall surfaces 1-1 and 1-2 in directions X and Y of the vibration table 1 and a supporting means for supporting the gravity of the vibration table 1. Each of the vibrating means in the direction X, for instance, has a construction wherein a bearing-part joining part 4-1 having a hydrostatic bearing provided at one end part of a vibrating shaft 2-1 is joined to a prescribed joining part with the vibration table 1 and a hydraulic guide 6-1 constituted of the hydrostatic bearing is provided around the intermediate part of the vibrating shaft 2-1. Moreover, a vibrating table 7-1 of the vibration generator 3-1 is fixed to the other end part of the vibrating shaft 2-1 and thus the vibrating means in a plurality of sets formed on a floor surface are constructed. The vibrating means in the direction Y are constructed in the same way as the above.
