Automobile leaf spring endurance fatigue testing machine

The endurance fatigue testing machine of automobile leaf spring can realize three-dimensional freedom dynamic (fatigue) loading test, which is mainly used for endurance performance test of three-dimensional freedom fatigue test of thrust rod, leaf spring, rubber-plastic joint, ball hinge and rubber elastomer. It can also be used for multi-directional composite tests of tensile, compressive, torsional and swinging components such as metal materials and their components.This system carries out various tests under sine wave, triangular wave, square wave, trapezoidal wave, oblique wave and user-defined waveform.The test software works in Chinese environment, has powerful data processing function, automatically saves test conditions and test results, and displays and prints random group test data, test curves and test reports that meet relevant national standards.According to the different test conditions, the following tests can be carried out:Simple tension-compression fatigue test/simple torsion fatigue test/simple swing dynamic test/tension-compression-torsion composite fatigue test/tension-compression-swing composite fatigue test/tension-compression-swing-torsion composite fatigue test, etc. This machine is a customized device, and the parameter picture is only for reference.
