The testing machine adopts a mechanical push-pull fatigue loading structure design and is loaded with a displacement control method. The eccentric displacement can be adjusted mechanically. Six stations work at the same time. It is driven by a variable frequency speed motor, has low power consumption, small temperature rise, and is easy and reliable to control. By replacing different types of elastic bar fatigue loading fixtures, various types of elastic bar fatigue test methods can be met. The testing machine has functions such as automatic shutdown with preset number of tests, automatic alarm shutdown for fracture, etc. It is currently the elastic fatigue testing machine with the highest testing efficiency and the most reliable testing results independently developed in my country in the rail transit industry.
