Abstract

The invention provides a tension platform for synchronous-radiation light source CT (computed tomography) imaging, and relates to a tension platform. The tension platform aims at solving the problem of failure to observe and study the crack generation and expansion process of the structural material under the function of external force by the traditional analysis method in situ and in real time; by adopting the synchronous-radiation X-ray CT imaging, the internal defect of a millimeter-level specimen can be observed and analyzed by using high penetration ability; the cracking process can be observed in situ on the synchronous-radiation CT imaging line station; the tension platform is not available in the prior art. The tension platform comprises a first positive and reverse screw rod, a lower clamp bearing block, an X-axis displacement adjusting mechanism, a Y-axis displacement adjusting mechanism, an upper clamp rotary shaft, an upper connecting clamp, a force sensor, a second positive and reverse screw rod, a drive motor, a worm, two worm wheels, two sliding block fixing plates, two rotary bodies with motor drive mechanisms, two rotary body connecting shafts, two flexible couplings, two clamps and four guide rail sliding blocks. The tension platform belongs to the field of tension of light source imaging.

Description

technical field [0001] The invention relates to a stretching table, in particular to a stretching table used for CT imaging of a synchrotron radiation light source. Background technique [0002] Synchrotron X-rays have become an important detection tool for modern science due to their advantages of high brightness, high energy, high coherence, and high collimation. Europe, America, Japan and my country have all built their own large scientific devices for synchrotron radiation. Among them, CT imaging is an important application of synchrotron radiation technology. This method can be used to realize non-destructive testing of the internal structure of samples such as materials, organisms, and minerals, and is widely used in research fields such as materials, biology, archaeology, and geology. [0003] The failure behavior of structural materials under external force has always been an important fundamental issue in the field of materials science, and its process can be divid...
