1. A formation method for liquid rubber composite nodes with middle damping holes, the formation method comprising:
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;
forming damping through holes which penetrate through the mandrel on 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 damping through holes,
wherein the mandrel is formed by taking a central axis of the mandrel as a bus and taking a saddle surface, which is high at both ends and low in a middle, as a rotating surface.
