辊压工艺参数对平板和套筒金属橡胶动态力学性能的影响
          
Effect of Rolling Process Parameters on Dynamic Mechanical Properties ofFlat and Sleeve Metal Rubber

摘    要
采用不同参数的辊压成形工艺制备平板和套筒金属橡胶试样,与冲压成形平板金属橡胶试样进行形貌与动态力学性能对比分析,并研究了辊压工艺参数对试样动态力学性能的影响。结果表明:相比于冲压成形,辊压成形平板金属橡胶试样的结构均匀且金属丝间勾连效果更好,损耗因子和动刚度更小;辊压平板金属橡胶试样的损耗因子随辊压转速的增大而增大,随压下率和进料角度的增大而减小,动刚度随压下率和辊压转速的增大而增大,随进料角度的增大而减小;辊压套筒金属橡胶试样的动刚度随激振频率、激振振幅和预紧间距的增大而减小,损耗因子随激振频率和激振振幅的增大而减小,随预紧间距的增大而增大。

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.
