1. Dynamic and static universal testing machine

The main machine of dynamic static universal testing machine adopts double column structure, the maximum static load is 5kn, the maximum dynamic load is 2.5kn, and the measuring range is 2-100%.

Electro hydraulic servo dynamic static universal testing machine

Functional features:

(1) The main engine adopts double column structure.

(2) Symmetrical cyclic fatigue tests should be carried out on metallic and non-metallic materials. At the same time, static tensile test can also be carried out.

(3) The measurement and control system adopts ad850 universal test card and ATOS servo valve, which can realize the automatic control of the whole test process and all keyboard operation.

(4) It has three control modes of load, displacement and deformation and smooth conversion function between them. It can automatically collect and process test data, draw test curve and print test report.

Applicable materials: various materials, parts, elastomers, rubber elastomers and shock absorbers, etc

Test items: tension, compression, bending, low cycle and high cycle fatigue, crack growth, fracture mechanics test

2. Fatigue testing machine

Fatigue testing machine is a machine that can test fatigue in various ways. According to the test frequency, it can be divided into low frequency fatigue testing machine, medium frequency fatigue testing machine, high frequency fatigue testing machine and ultra high frequency fatigue testing machine.

High frequency fatigue testing machine

Applicable materials: metal, alloy materials and their components (such as operating joints, fasteners, spiral moving parts, etc.)

Test items: fatigue characteristics, fatigue life, pre crack and crack propagation test of tension, compression or tension compression alternating load at room temperature

Note: the electromagnetic high frequency fatigue testing machine can not be used for the fatigue test of composite materials, because the electromagnetic type is driven by the principle of electromagnetic resonance, which is related to the rigidity of the sample, so the composite materials can only be driven by the motor for the fatigue test.

3. Impact testing machine

Impact testing machine (English Name: impact testing machine) refers to the material testing machine that applies impact test force to the sample to carry out impact test. The impact testing machine is divided into manual pendulum impact testing machine, semi-automatic impact testing machine, digital impact testing machine, microcomputer controlled impact testing machine, drop weight impact testing machine and non-metallic impact testing machine.
