The Develop Of Multi-Purpose Test Instrument For Brittle Materials Mechanics Performance Perforance Testing

The brittle material such as glass, ceramics, concrete is a very important kind of structural material in the national economy construction, however, as a result of its brittleness, this kind of material is also easiest to occur accident, and is regarded as the most unsafe material. The accidents causing by brittle material bring enormous loss to our national economy and people's property every year. Certainly, the security of brittle material causes more and more people's attention. How to carry out more effective function test to brittle material, especially the mechanics function test, even further to measure online in active service state seems particularly important and urgent.The multi-purpose tester developed here is aim at testing the mechanics performance of the brittle material, which bases on modular design thought,it contains several modules as the machinery load component, platform of supporting, the function modules and the software system, they can be combined in different function modules to Satisfies the need of different application situation. The tester can be used to measure not only general material properties such as elastic modulus, ultimate strain, strength, hardness and toughness, fatigue properties but also various special properties such as the local strength, and surface residual stress at the different location of the brittle component with non-destructive methods. Thus the security and reliability of the brittle component can be evaluated and predicted.The article starts from elaborating the thought of design and contrast of plans, which is based on considering the background and the request of the project. Then introduces the choice of design plan and composition & principle of various modules, the article has paid more attention to the design and calculation of the machinery load component and platform modules. Moreover, the article has carried on exhaustive narration to the design of transmission system, specially the choice and the computation to the key parts of transmission system in order to satisfy the request of the whole system. In the process of designing, we establish the whole system modeling through UG first, and then utilizes ANSYS to process finite element analysis on the main distortion parts,...
