Claim 3:
4. The formation method for liquid rubber composite nodes with middle damping holes according to claim 2, wherein a bump protruding towards the mandrel is arranged on an inner circumferential arc surface of the arc cover plate; the bump comes into contact with a rubber covered on an outer circumferential surface of the mandrel to provide nonlinear stiffness, and the bump comes into indirect contact with the mandrel to form hard stop limiting, or
mandrel bumps are arranged on the mandrel, and the rubber is covered on the mandrel and the mandrel bumps; the arc cover plate comes into contact with the rubber located in the liquid cavities and covered on the mandrel and the mandrel bumps to provide nonlinear stiffness, and the arc cover plate comes into indirect contact with the mandrel bumps to form hard stop limiting, or
rubber bumps protruding towards the arc cover plate are arranged on the rubber located in the liquid cavities and covered on the outer circumferential surface of the mandrel, and the arc cover plate comes into contact with the rubber bumps to provide nonlinear stiffness.
