The Railway Locomotive Spring Testing Machine is specially designed for mechanical performance testing of high-speed railway springs, railway vehicle springs, locomotive springs, large wire diameter springs, and air springs.The machine is capable of testing the axial load, lateral displacement, lateral force, and lateral stiffness of the primary and secondary suspension coil springs used in CRH series high-speed electric locomotives.The entire testing process is controlled by a computer system and completed automatically. The equipment can automatically analyze parameters such as bending direction and stiffness values, and generate and print axial load–deformation (deflection) curves and lateral force–lateral displacement curves.It features high testing accuracy, automatic data processing, convenient operation, and reliable performance, making it suitable for railway vehicle manufacturers, spring manufacturers, and quality inspection laboratories.

The Railway Locomotive Spring Testing Machine is mainly used for mechanical performance testing of high-speed railway springs, locomotive springs, railway vehicle suspension springs, large wire diameter springs, and air springs.
It is widely applied in:
Railway vehicle manufacturing: Testing the performance of primary and secondary suspension springs of locomotives and high-speed trains.
Spring manufacturing industry: Quality inspection and performance verification of large-size compression springs and special springs.
Railway maintenance and inspection: Evaluating spring fatigue performance, stiffness, load characteristics, and service reliability.
Research and testing laboratories: Conducting mechanical property analysis and product development tests.
The machine can test key performance parameters including axial load, axial deformation, lateral force, lateral displacement, stiffness, and load-displacement characteristics. It can automatically generate and analyze axial load–deformation curves and lateral force–displacement curves.
