The tubular belt dynamic bending fatigue performance testing machine, according to the actual application of the tubular conveyor belt, carries out the dynamic bending fatigue test of the sample in the state of small tension. Through the machine test, the rigid fatigue performance of the tubular belt is reflected, and the design parameters are provided for the production of the tubular belt. The machine uses the touch screen and PLC communication mode to carry out process sequencing control. The tension is applied by AC servo system and can be controlled by constant tension. The specification of the roller can be changed according to the sample, and the operation data can be exported, printed and saved via USB flash disk.
