Shock absorber spring knowledge 2020-08-14 15:18:11
Damping spring is a commonly used elastic component, widely used in various vibration equipment, automobile manufacturing and other industries, with good stability, low noise, good vibration isolation effect, long service life and other advantages.
Performance standard and function of torsion fatigue testing machine 2020-08-13 10:20:44
Torsional fatigue testing machine refers to the use of electro-hydraulic servo, electro-magnetic resonance, hydraulic, electric and other exciting mode, equipped with a suitable control system, can be within a certain frequency range, the sample applied cyclic torque testing machine.The testing machine usually includes torsion system, torque measurement system, extensometer system, control system and data acquisition system.In addition, according to the different USES of the testing machine, you can also choose a variety of accessories.The torsional fatigue testing machine is mainly used to measure the fatigue characteristics or fatigue life of metal and non-metal materials and their components (such as transmission shaft, half shaft, belt wheel, etc.) under the condition of alternating torque.
Classification of spring testing machines 2020-08-12 10:49:53
After spring produce, before use, through rigorous testing to be put into use, because spring is most used in above the main components of machinery, vehicles, such as the spring on the vehicle, if installed in the car did not pass the strict test of the spring, literally in the vehicle used above, performance is not up to par, that would be easy to cause very serious consequences;
What are the functional features of the horizontal spring torsion testing machine 2020-08-11 09:36:13
The horizontal spring torsion testing machine is suitable for testing the torsional Angle and torsional moment of all kinds of large springs. The torsion resistance test of parts and components can also be carried out by adding corresponding attachments.
