Abstract:
Flat and sleeve metal rubber specimens were prepared by rolling forming with different process parameters. The morphology and dynamic mechanical properties of the rolled flat specimen were analyzed and compared with those of the stamped flat metal rubber, and the effect of rolling process parameter on the dynamic mechanical properties of the specimens was studied. The results show that compared with those by stamping forming, the structure of the rolled flat metal rubber specimen was uniform, the effect of metal wire hooking was better, and the loss factor and dynamic stiffness were lower. The loss factor of the rolled flat metal rubber specimen increased with the increase of rolling speed, and decreased with the increase of reduction rate and feeding angle, while the dynamic stiffness increased with the increase of reduction rate and rolling speed, and decreased with the increase of feeding angle. The dynamic stiffness of the rolled sleeve metal rubber specimen decreased with the increase of excitation frequency, excitation amplitude, and preload distance, while the loss factor decreased with the increase of excitation frequency and excitation amplitude, and increased with the increase of preload distance.
