Description

technical field [0001] The invention relates to the technical field of testing, in particular to a test platform for comprehensive performance of shaft tension and compression, bending, torsion and vibration. Background technique [0002] Since the birth of human civilization, materials have been closely related to human life. With the rapid development of industrial science and technology, materials not only penetrate into people's daily life, but also have been widely used in aerospace, marine engineering, biomedical engineering, mechatronics, microelectronics and other fields. Due to insufficient research on the damage mechanism and performance evolution of materials under actual use conditions, material failures occur frequently due to improper material selection or untimely maintenance, and the resulting major accidents are too numerous to enumerate. It hinders the effective use of resources and seriously threatens the safety of people's lives and properties. [0003]...

AI Technical Summary

Problems solved by technology

[0004] At present, most material performance testing instruments are limited to single mechanical properties, or based on static and dynamic loading. Traditional testing methods cannot fully study the performance of materials under actual complex working conditions. The mechanical properties and damage mechanism under the combined loads of tension, compression, bending, torsion, and vibration, the comprehensive performance test that simulates the stress state of materials under different working conditions, and provides a theoretical basis for the application of materials is of great importance to the application of materials. The guiding role, to a certain extent, promotes the exploration of the deformation and damage mechanism of materials under actual complex working conditions, and will also have a positive effect on the development of society and economy

It solves the problems of complex operation and poor compatibility in the current technology, and has the characteristics of simple operation, high integration, compact structure, diversified test modes, and rich test content.
