Abstract

The invention provides a uniformly distributed load test device, which comprises a homogeneous flexible bag placed on a test piece, wherein the size of the bottom surface of the homogeneous flexible bag is the same as that of the surface of a uniformly distributed load area of the test piece; and a meter that is connected with the homogeneous flexible bag so as to control the flow of the liquid filled into the homogeneous flexible bag. According to the uniformly distributed load test device provided by the invention, by arranging the homogeneous flexible bag, the size of the bottom surface of the homogeneous flexible bag is designed to be the same as the size of the surface of the uniformly distributed load area of the test piece, and uniform load on the surface of the test piece is realized by utilizing the liquidity of liquid; in addition, by arranging the meter, the meter controls the flow of the liquid filled into the homogeneous flexible bag, and accurate and uniform load distribution and application are achieved. Compared with manual weight stacking, the uniformly distributed load test device provided by the invention has the advantages that the load distribution on the surface of the test piece is more uniform, and the precision of the applied load is more accurate and flexible.

Description

technical field [0001] The invention relates to the technical field of uniform load test, in particular to a uniform load test device. Background technique [0002] Usually, the uniform load test for light-weight plates or components is mainly carried out in the form of uniform load, manual stacking of weights, and five-level loading. It is divided into light-weight partition wall strips for bending load and metal surface cored panels. There are two types of flexural capacity. [0003] The loading method of bending resistance is: support the light plate or component to be tested on two parallel supports whose length is greater than the width of the plate, and the center of the support is 50mm away from the end of the plate. According to no less than 5 levels, use the stacking method, that is, manually add weights to apply the load evenly from both ends to the middle. The load of each level is not more than 30% of the self-weight of the plate, and the fifth level is added t...
