Abstract
A formation method for liquid rubber composite nodes with a tubular flow channel is provided. The formation method includes adding a middle spacer sleeve between an outer sleeve and a mandrel, bonding the middle spacer sleeve and the mandrel together through rubber vulcanization and assembling the integrated middle spacer sleeve and the mandrel into the outer sleeve; installing a tubular flow channel in the mandrel; hollowing the middle spacer sleeve to form a plurality of spaces; after vulcanization, forming a plurality of interdependent liquid cavities by using rubber and the plurality of spaces; and arranging liquid in the plurality of liquid cavities and communicating the plurality of liquid cavities through the tubular flow channel.
