With the rapid development of high-speed railways and the increase in train speeds, more comfort and safety and stability are now pursued. Usually high-speed train bogies will use axle box springs and air springs to improve safety and comfort.so the quality of the spring determines the safety of the train.
The spring tension and compression testing machine performs various tension and compression tests to ensure the quality of the spring.the control software can automatically calculate the technical index and conventional data required by the spring, and can automatically calculate the force, stress, displacement, deformation and other data results at any specified point in the test process. It can also measure the compliance, elastic coefficient, and freedom of the specified height of the spring. Parameters such as height.
At present, a variety of spring tension and compression testing machines have been provided for China's high-speed railways, which guarantee the safe operation of high-speed railway trains.
