Abstract

This utility model discloses a fatigue testing device for subway handrails, including a test frame, a mounting mechanism, and an actuator. Both the mounting mechanism and the actuator are mounted on the test frame. The mounting mechanism secures the handrail to the test frame, and after securing, the actuator connects to the handrail, enabling fatigue testing of the handrail. A control system is also located on one side of the test frame, and the actuator is electrically connected to the control system, allowing control of the actuator. This utility model achieves automatic fatigue strength testing of subway handrails, improving testing efficiency while allowing for periodic loading and releasing, and setting of load values ​​and cycle counts. This more closely simulates the load-bearing conditions of the handrail during use, improving testing accuracy. Furthermore, the structure of this application is relatively simple, easy to operate, and effectively reduces testing costs.
