First, the use of stress fatigue testing machine:
Slow strain rate stress corrosion testing machine is mainly used to measure the tensile and compressive fatigue characteristics of metal materials and their components under dynamic loads such as sine wave, triangle wave, square wave and oblique wave. The following types of test projects can be completed: Tensile fatigue test, tensile fatigue test, compressive fatigue test, fracture toughness test, crack growth test, stress fatigue test, strain fatigue test, In line with GB/T2611 "Testing machine general technical requirements", GB/T16826 "Electro-hydraulic servo wan energy testing machine", GB3075 "Metal axial fatigue test method", JB/T9397 "tensile fatigue test machine technical conditions", GB228 "Metal material room temperature tensile test method" and other test standards.
Second, slow strain rate stress corrosion testing machine host parameters:
1. The maximum axial test force: 10KN, 20KN, 25KN, 50KN, 100KN, 200KN
2. Test force level: ±1%;
3. Test force measurement range: 2%--100.%FS;
4. The maximum displacement of electro-hydraulic servo actuator: ±50mm/75mm;
5. Electro-hydraulic servo valve frequency range: 0.1-50 Hz (optional);
6. Frame form: double columns; Column distance: ≥600mm; Upper and lower chuck spacing: 50 ~ 600 mm;
7. Control system: all digital electro-hydraulic servo controller based on PCI bus;
8. Control mode: force, displacement two closed loop control loop, can achieve full digital PIDF control, control mode can be smoothly switched. Full digital DSP control system, closed-loop control frequency: 1kHz;
9. Full digital internal signal generator: sine wave, triangle wave, square wave, oblique wave, combination wave, etc.
Third, Remarks:
1. The performance characteristics of the fatigue testing machine are detailed in the "Equipment recommendation";
2. Fatigue testing machine all kinds of fixtures and measuring devices and other accessories, according to customer requirements;
3. The use of fatigue testing machine space structure or stroke size can be customized according to user requirements;
4. Can be equipped with high temperature furnace, low temperature box, corrosion box and other environmental boxes, to complete the mechanical test of materials in different environments.
