Universal testing machine is based on the national standard GB/T 16826-2008 "electro hydraulic servo universal testing machine design and manufacturing". The host adopts highrigidity design, each stress components by the finite elementanalysis, design, precision machining and testing. Oil source system by using the load adaptive throttle speed controlsystem, after repeated compression test and maximum loadand load test. The controller uses a new generation of high performance, intelligent digital independent controller, control software adopts the advanced control algorithm combination,can accurately control the whole process of the experiment,fully meet the test method of the domestic and internationalmaterial requirements. The main function of universal testing machine:

万能试验机是测试各种材料及其制品在各种环境和模拟状态下的物理性能、机械性能、工艺性能、结构抗震强度以及材料与构件内外缺陷的重要仪器设备。可以按照相应标准实现对金属或非金属材料的拉伸、压缩、弯曲、剪切等类型的试验，可以求取所测材料的抗拉强度、屈服强度、规定非比例延伸强度、弹性模量等性能指标，可实现等速率加荷、等速率变形、等速率位移、等速率应变等闭环控制，可以进行材料或产品的工艺合格性能验证试验。

Universal testing machine is physical properties, testing of various materials and products in a variety of environment and the simulation state mechanical properties, process performance, seismic intensity structure as well as thematerials and components of internal and external defects in an important instrument and equipment. In accordance with the corresponding standards, tensile test of metal or non-metal materials compression, bending, shear type, can be obtained from the measured tensile strength, the yield strength of the material, specified non proportional extension strength, elastic modulus and other performance indicators,realizing rate loading, constant rate deformation,displacement, velocity constant the strain rate of closed-loopcontrol, the process can be material or product qualifiedperformance verification test.

万能试验机的设计考虑了扩展装配其它夹具以完成更多试验的可能。如：配装螺栓夹具可做螺栓的拉伸和保载，配装剪切夹具可做圆棒剪切强度试验，在压缩空间中加配抗折、剪切、劈裂、弹性模量仪等可做混凝土及水泥样块试验，配上钢球、锚链、扣件等专用夹具可完成相应产品的各项试验。

Design of universal testing machine considering the assemblyfixture to complete the expansion of other more trials may.Such as: tensile loading bolt to bolt clamp and holding, withshear fixture can be round bar shear strength test, in the compression space is added to the flexural, shear, splitting,elastic modulus tester to do concrete and cement sample test,with special fixture, the ball, to be completed by thecorresponding experiments. Products.
