| description | The invention discloses a cantilever bending type rotary bending fatigue test device, and relates to the technical field of metal material fatigue performance testing. The device is mainly composed of a permanent magnet synchronous motor, an elastic chuck, a Hall sensor, a temperature sensor, a conical connecting rod, a steel cable, a high-frequency camera, a ball screw transmission device and the like. The two ends of the test bar are fixedly connected with the motor driving shaft and the conical connecting rod through elastic chucks respectively. The actuating mechanism of the device performs two-degree-of-freedom motion, namely high-speed rotating motion and downward bending of the test bar. According to the mechanism principle of the device, a vertically downward pulling force is applied to a cantilever beam model composed of a motor driving shaft, an elastic chuck, a conical connecting rod and a small bearing seat in a linear pulling force applying mode, a test bar is bent downwards to generate bending s |
