Industrial CT scanning test system

Abstract

The invention discloses an industrial CT scanning test system, which comprises a test base, a multi-axis movement rotation table, a ray generation device, an image acquisition device, a fluid pressure loading device and a control device, wherein the multi-axis movement rotation table, the ray generation device, the image acquisition device and the fluid pressure loading device are supported on the test base. According to the present invention, the industrial CT scanning test system uses the fluid pressure loading device so as to reduce the self-weight of the loading device as much as possible and provide the high loading force, such that the requirements of most of the rock material deformation and failure tests can be met; the loading cylinder of the loading device performs the real-time loading on the sample on the sample table of the multi-axis movement rotation table, such that the loading force applied on the rock sample by the loading cylinder can be real-timely regulated according to the test requirements so as to improve the test efficiency; and according to the number of the arranged loading cylinders, the applying of the multi-direction loading force on the sample can be achieved.

Description

technical field [0001] The invention relates to the technical field of sample scanning, in particular to an industrial CT scanning test system. Background technique [0002] Industrial CT (Computed Tomography) scanning technology provides an effective experimental technique for analyzing and studying the internal structure of materials, and has been widely used in various related fields. [0003] The current industrial CT usually uses X-rays to penetrate the section of the object for rotating scanning and realizes the reconstruction of the internal image with the help of a high-performance computer system. The principle is to measure the radiation intensity of X-rays after penetrating the object under inspection through a specific detector, and at the same time complete the scanning movement between the X-ray machine, the detector and the object under inspection, so as to obtain the complete data required for reconstructing the CT image. Finally, according to a certain algo...

Problems solved by technology

However, for the mechanical loading analysis of rock and soil materials, the following challenges need to be overcome: First, the sample should not be too small, otherwise it will be affected by the size effect and the required experimental results cannot be obtained, and the increase of the sample will inevitably cause the loading device to be damaged. increase, which will bring about a series of problems such as difficulty in ray penetration, increase in loading tonnage, and decrease in image resolution; second, the loading system is often more complicated. Axial tension and compression experiments are not enough, and multiple complex loading experiments such as multiaxial compression, seepage, hydraulic fracturing, etc. are also required, and sometimes multiple loading and unloading procedures are required, so the realization and control of the loading device has higher requirements Require
