Abstract

With the continuous development of science and technology, the

requirements of mechanical products have become more

sophisticated.Mechanical products need to meet the needs of society, they should have high accuracy, high efficiency, versatility and flexibility performance．Coupled with the condition that upgrading speed of mechanical products is accelerating,so the machine equipment is raised correspondingly high precision, high efficiency, good versatility and flexibility requirements. Electronic universal testing machine，as a high-end product of the CNC machine tool family ，is being more and more used in the field of modern machinery industry ,its capacity with Beautiful models, Simple Operation , high precision, High efficiency, high versatility features.

Testing machine plays an important role on today's Machining Center, whose reliability has a huge effect on machine reliability. In order to improve the MTBF level of Machining Center, it is significant to invent a testing bed to test the reliability of Various materials.

The article is the strutural design of the 1KN tension and compression testing machine.the test rig design ontologies modeled on the WDW-100C-1000C, the structure can meet the requirement of the Requirements of the corresponding parameters.The strength and stiffness of important part of test bench is simulated by analysis software to meet the reliability test requirements.

Keywords：Maching Center； Reliability；Tensiler；Structural Design
