Title:
THREE AXIAL DIRECTIONS VIBRATION COMPOUND TESTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/091535
Kind Code:
A1
Abstract:
A three axial directions vibration testing apparatus has a working table (20), a second axial vibration transmitting mechanism (25) in the horizontal X-axis direction and a third axial vibration transmitting mechanism (26) in the horizontal Y-axis direction which are cross straight line rail sets, and a first axial vibration transmitting mechanism (24) in the vertical Z-axis direction which connects with a Z-axis direction vibration generator (21).The first axial vibration transmitting mechanism (24) includes an upper-clamping plate(27), a lower clamping plate (28) and a middle interposing plate (29),the upper and lower clamping plates (27,28) are opposed to each other horizontally, the middle interposing plate (29) lies between them, and the middle interposing plate (29) is clamped by the upper and lower clamping plates (27,28). The lower surface of the upper clamping plate (27) and the upper surface of the middle interposing plate (29) form an upper mating surface by clearance fit; the upper surface of the lower clamping plate (27) and the lower surface of the middle interposing plate (29) form a lower matching surface by clearance fit. High pressure fluid is fed into the clearance of the upper matching surface and the clearance of the lower matching surface to form a static pressure fluid membrane (45) and to make a static pressure plane bearing structure. The middle interposing plate (29) fixedly connects with the working table (20), the upper clamping plate (27) or the lower clamping plate (28) fixedly connects with the Z-axis direction vibration generator (21).The three axial directions vibration testing apparatus has simplified structure, it can reduce the cost and increase the ability of resisting turning torque.
