Title:
HIGH-DAMPING STIFFNESS-VARIABLE LATTICE COMPOSITE STRUCTURE SHOCK ABSORBER, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/078476
Kind Code:
A3
Abstract:
A high-damping stiffness-variable lattice composite structure shock absorber, and a preparation method therefor. The shock absorber is composed of a lattice composite structure and a base, wherein the lattice composite structure is formed by compositing a lattice metal and a viscoelastic material. The adjustment and control range of the porosity of the lattice metal is 30-90%; the hole edge diameter of the lattice metal is 1-3 mm; and the minimum hole diameter is 0.8-2.5 mm. The matrix material of the lattice metal is a steel material; and the matrix material of the viscoelastic material is an epoxy resin or polyurethane. By means of the effective adjustment and control to the hole shape parameters and porosity of the lattice structure, the rigidity of the shock absorber is adjusted between an elastic connection and a rigid connection, such that the inadequacies of the elastic connection and the rigid connection are overcome; and the lattice structure is filled with the viscoelastic material by means of a seepage and vacuum auxiliary technology, so that the problems of poor interface bonding of the viscoelastic material to the metal, lattice metal being insufficiently filled with the viscoelastic material, and bubbles being prone to being generated inside the viscoelastic material and the interface between the viscoelastic material and the metal are solved by means of material modification and process adjustment and control.
