Problems solved by technology

And because the top of the special component is fixed on the top of the universal testing machine by bolts, it is not conducive to the connection of test components of different shapes and sizes with the special component in operation, and the operation of the special component is more complicated, and the specific steps and sequence of the operation must be kept in mind process

Embodiment Construction

[0014] Referring to the accompanying drawings, the experimental component applied on the universal testing machine to apply the axial load to fix the support includes a top seat 1 and a base 2. The bottom of the top seat 1 is fixedly connected with a hemisphere 3 by bolts, and the outer wall of the hemisphere 3 is fixed at intervals There are four upper supports 4, and the base 2 is provided with a spherical groove 6 corresponding to the semicircular ball 5, and the side wall of the base 2 is fixedly provided with a lower support 8 corresponding to the upper support, and the upper support 4 is connected to the lower support. Suspenders 7 are connected between the supports 8, and the suspenders 7 are threadedly connected with the upper support and the lower support. Cross-line mounting holes 9 are distributed on the base, and the upper support and the lower support are L-shaped.

[0015] First, the top of the special component is fixed above the universal testing machine by bolt...

Abstract

The invention discloses a test member capable of providing axis load fixed support for a universal testing machine. The test member capable of providing the axis load fixed support for the universal testing machine comprises a top seat and a base. A semicircular ball is fixedly connected with the lower portion of the top seat through bolts. Four upper supports are fixedly arranged on the outer side wall of the semicircular ball at intervals. A ball-shaped groove which corresponds to the semicircular ball is formed in the base. Lower supports which correspond to the upper supports are fixedly arranged on the side wall of the base. Booms are connected between the upper supports and the lower supports. The booms are connected with the upper supports and the lower supports in a threaded mode. The test member capable of providing the axis load fixed support for the universal testing machine is capable of effectively avoiding influences on analog fixed support boundary condition and function susceptibility of providing axis load by the special member which is applied to the bottom of the test member to simulate fixed support boundary axis load due to the size of the semicircular ball, being conveniently applied to the test members with different sizes due to the fact that the manufactured special member with the appropriate size is fixed at the upper portion of the universal testing machine and effectively saving test cost.

Description

technical field [0001] The invention relates to the field of structural testing, in particular to an experimental component applied to a universal testing machine and fixedly supported by an axial load. Background technique [0002] As we all know, in structural tests, fixed support is one of the most commonly used boundary conditions, and its application is also the most extensive in building structures. However, how to correctly and effectively simulate the supported boundary conditions in structural tests is not a simple problem. At present, many structural tests carried out in China, especially in the axial compression test, do not correctly and effectively simulate the boundary conditions of fixed supports, but directly place the test components in the universal testing machine for the compression test rather roughly. , in fact, it does not consider what kind of boundary condition the test component is in, and effectively constrains its boundary. As a result, the test...
