Title:
FULL LOAD STATIC CHARACTERISTICS TESTING DEVICE FOR BOLT JOINT SURFACE UNIT AND TESTING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/013137
Kind Code:
A1
Abstract:
A full load static characteristics testing device for a bolt joint surface unit comprises a box body (1), a cross beam (7) is set above the box body (1), the cross beam (7) is fixedly connected with the box body (1) through a left upright post (4A) and a right upright post (4B); a lower test piece (2) is arranged on the table surface of the box body (1), an upper test piece (3) is arranged on the lower test piece (2), a preload component (6) is set between the upper test piece (3) and the cross beam (7), the preload component (6) connects the upper test piece (3) with the lower test piece (2) sequentially; a first load applying component (5A) and a second load applying component (5B) are vertically and respectively set on the cantilevers at two ends of the upper test piece (3) symmetrically, the first load applying component (5A) and the second load applying component (5B) are respectively connected vertical upwards to the cross beam (7); the termials of the cantilevers at two ends of the upper test piece (3) are respectively provided with a connecting piece (8), a third load applying component (5C) and a forth load applying component (5D) are horizontally and which respectively set between each connecting piece (8) and the right upright post (4B) and the left upright post (4A) of the cross beam (7). A full load static characteristics testing method for a bolt joint surface unit can be used for performing pre-tightening force test, normal working load static characteristics test, tangential working load static characteristics test, bending moment working load static characteristics test and torque working load static characteristics test of the bolt joint surface unit by utilizing the combination of different configuration of testing device mentioned.
