Real-time image observation and acquisition platform and method for microstructure of material with loads

Abstract

The invention discloses a real-time image observation and acquisition platform and method for the microstructure of a material with loads. The platform comprises a loading device, an image observation and capture device and an XY double-coordinate micro-control mobile device and a PC, (Personal Computer), wherein the image observation and capture device is fixedly connected onto the XY double-coordinate micro-control mobile device; the XY planes of the XY double-coordinate micro-control mobile device are parallel to the surface to be observed of a material; the image observation and capture device and the loading device are respectively connected with the PC through data lines. The method comprises the following steps: dynamically capturing the images of the microstructure of the material with the loads, and associating a universal material testing machine sensor to synchronously obtain mechanics data; causing the PC to track the mechanics data flow acquired by the sensor, recognize a key point and trigger the image observation and capture device to take pictures; in the late, realizing correlation analysis of the data and the images through a computer and modeling. The acquisition platform and the method perfect the analysis method of mechanics of materials, disclose the damage evolution mechanism of materials, and provide a new method for study of damage mechanics of materials.

Description

technical field [0001] The invention relates to an image acquisition platform and method, in particular to a real-time image observation and acquisition platform and method for the microstructure of materials under loading, belonging to the field of microscopic image observation, acquisition and analysis. Background technique [0002] The study of the internal stress-strain law of materials under load has important guiding significance for the design and operation of precision mechanical equipment. The traditional method mainly observes and compares the static behavior of the material's macroscopic or microscopic structure before and after loading, and cannot obtain the dynamic changes of the internal structure during the loading process. Along with the dynamic interaction between the mechanism and the material and the need for adaptive control of the mechanism, it is necessary to clarify the law of the transfer and attenuation of the load in the material structure during th...
