Embodiment Construction
[0019] The variable cross-section phononic crystal elastic material is composed of a copper block and a rubber column. It is characterized in that the copper block and the rubber column are first bonded with glue, then copper pressing sheets are added, and then fixed with bolts. The thickness of the copper pressing sheet is 0.5mm-1mm, the outer diameter is 0.2mm smaller than the groove of the copper block, and the inner diameter is 0.2mm larger than the rubber column.
[0020] The assembly process is:
[0021] (1) Apply glue to the flange of the rubber column and the groove of the copper block first.
[0022] (2) Put the rubber column flange into the groove of the copper block, the threaded holes of the two must match, and then bond.
[0023] (3) Put the copper pressing piece into the rubber column, and then fix the three with bolts.
[0024] (4) Assemble each interface in sequence.
