Pressing Characteristics of Metal Rubber Material and Influence on Its Structural Performance

Combined with the pressing test of cylindrical metal rubber components, the variation law of the force between the metal rubber blank and the die during the pressing process, as well as the influence on its density distribution and elastic recovery value were discussed. The results show that the pressure increases exponentially with the increase of relative density in a wide range, and a large part of it is consumed by the contact friction between the die inner wall and the blank surface. The uneven density distribution of metal rubber is caused by contact friction, which is the main reason for the instability of metal rubber components. For metal rubber components with large bearing area and long length, multiple metal rubber components in parallel or series can be used.
