Full load static characteristic test apparatus and test method of bolt joint surface unit

摘要

And a case (1), the cross beam (7) is installed on the upper case (1), the cross beam (7) the left strut static characteristic test apparatus of the total load of the bolt joint surface unit of the present invention and (4A) It is firmly connected to case (1) the right strut through (4B), under the test element (2) is arranged on the worktable case (1), under the test element (2) on the upper test member (3 ) is located, is installed (6) preload parts that bind to Ji order above test member (3), under test member (2) and (7) between the cross beam and the upper above test member (3), above load application parts one mounted symmetrically each cantilever across the test member (3), referred to as (5B) the second load application part the first load application parts and (5A), respectively, the first load application each coupled cross beam (7) in the vertical upward (5B) the second load application parts and (5A) parts, the ends of the cantilever across the upper test member (3) coupling member each one (8) It is attached to the right strut 4B between (8) cross beams (7) coupling members, the left strut (8) cross beams (7) coupling member in (4A) between the load application component to be horizontal, each installation It is referred to as (5D) fourth load application part 3 and the load application part (5C), respectively. By using a combination of different structures the test apparatus, prestressing force test of bolt joint surface unit, use static load characteristic test in the normal direction, static characteristic test method of total load of the bolt joint surface unit used in the tangential direction it is possible to carry out the working load static characteristic test of torque and use static load characteristic test of the moment load static characteristic test, bending.
