Bed fatigue test controller for light, mechanical and electronic integration medical instrument

Abstract

The invention discloses a bed fatigue test controller for a light, mechanical and electronic integration medical instrument, belonging to the technical field of light, mechanical and electronic integration. The bed fatigue test controller comprises a base, wherein support pillars are respectively arranged on the left side and the right side of the bottom part of the base; support frames are respectively arranged on the left side and the right side of the top part of the base. Compared with an existing bed fatigue test controller for the light, mechanical and electronic integration medical instrument, the bed fatigue test controller for the light, mechanical and electronic integration medical instrument, provided by the invention, adopts ultrasonic fatigue testing; compared with other fatigue testing machines, the test frequency of an ultrasonic fatigue testing machine is larger, so that a test result is more accurate; in addition, on the basis of the existing bed fatigue test controller for the mechanical and electronic integration medical instrument, an image acquisition sub-system and an image analysis sub-system are added, so that a direction and speed of crack propagation of a sample can be analyzed and calculated through real-time monitoring the sample when the sample is subjected to fatigue test, the force analysis is cooperatively carried out on the sample, and thus analyzed data is more accurate.

Description

technical field [0001] The invention relates to the technical field of opto-mechanical integration, in particular to a bed fatigue test controller for an opto-mechanical-electrical integrated medical device. Background technique [0002] The fatigue testing machine is used to test whether the material will break suddenly without significant appearance deformation after repeated or alternating stress. Statistics show that about 60% to 80% of the fractures in aerospace engineering are caused by fatigue damage of structural materials. Because the current technology cannot theoretically predict the strength performance of materials under variable loads, the fatigue limit and fatigue life of materials under variable loads can only be temporarily used to replace the index of dynamic strength performance. Fatigue tests are widely used in aerospace, automobile, shipbuilding, metallurgy, construction and other industries, and are closely related to product quality and personal safet...

Problems solved by technology

[0003] The object of the present invention is to provide a kind of controller of bed body fatigue test for optomechanical-electrical integration medical equipment, to solve the above-mentioned common medical equipment bed fatigue test machine that proposes in the above-mentioned background technology only only to the stressed data of sample. Collection and analysis, instead of collecting and analyzing the crack changes generated by the sample when it is stressed, the problem that the data obtained after the analysis is not accurate enough
