[0002] A turnout is one of the key technical equipment of a monorail system, which can realize the line change, turning-back operation of a vehicle during driving and the shunting operation of a vehicle in a depot or a parking lot. As one of the important load-bearing components of a monorail vehicle system, the failure form of a turnout is mostly fatigue failure caused by random loads, and the failure form is high-cycle fatigue failure, that is, stress fatigue failure. There are certain limitations in studying the fatigue life problem of a monorail turnout from the perspectives of pure theoretical analysis and simulation software. It is necessary to further obtain a large amount of test data through physical turnout tests to improve the research on the turnout fatigue failure problem.
[0003] Based on the above, the inventor found the following problems: The existing multi-functional turnout rail fatigue test bench cannot conduct fatigue tests with different degrees on different positions of the turnout rail.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a multi-functional turnout rail fatigue test bench is provided, with the expectation of achieving a more practical value. Summary of the Utility Model

Furthermore, the relative position between the base and the rail can be adjusted, and the lateral actuator can be adjusted to perform fatigue tests on different positions of the side surface of the rail. And by adjusting the distance between the bases on both sides of the rail and then making the lateral actuators on a pair of bases operate simultaneously, the toughness of the rail can be detected.
