1. According to classification methods, they can be divided into metal material testing machines, tensile testing machines, non-metal material testing machines, dynamic balancing testing machines, vibration tables, and non-destructive testing machines, etc. Among these, the loading methods, structural features, force measurement principles, and application ranges of material testing machines vary.
2. According to the loading method, they can be divided into static load testing machines and dynamic load testing machines. Static testing machines mainly include universal testing machines, hydraulic universal testing machines, electronic universal testing machines, pressure testing machines, tensile testing machines, torsion testing machines, and creep testing machines. Dynamic testing machines mainly include fatigue testing machines, dynamic-static universal testing machines, unidirectional pulsating fatigue testing machines, impact testing machines, etc.
3. According to the force measurement method, they can be divided into mechanical force measurement testing machines and electronic force measurement testing machines.
4. According to the control method, they can be divided into manually controlled and microcomputer servo controlled testing machines; according to the cylinder position, they can be divided into cylinder-top and cylinder-bottom type testing machines.
5. Classification by test force: 5KG, 100KG, 500KG, 1T, 2T, 3T, 5T, 10 tons, 20 tons, 30 tons, 50 tons, 60 tons, 100 tons, 200 tons, 300 tons, 500 tons, 1000 tons. What are the classifications of universal material testing machines?
