Additive manufacturing viscoelastic damping device
The invention relates to the technical field of vibration reduction, shock resistance and rapid prototyping manufacturing of engineering structures, and discloses an additive manufacturing (3D printing) viscoelastic damping device which comprises an outer side constraint steel plate, a middle steel plate and a high-performance damping material. The two layers of damping materials are symmetrically arranged on the two sides of the middle steel plate, and the inner steel plate and the outer steel plate are arranged on the outer sides of the damping material layers. Wherein the high-performance damping material is a 3D printing high-molecular polymer, and is prepared by extruding a printing material from polyurethane through FDM (fused deposition modeling); the middle steel plate and the outer side steel plates are additive manufacturing steel plates and are manufactured by adopting steel powder through LAM (laser additive manufacturing). The steel plate and the damping material which are manufactured respectively are combined into the whole damping device in the mode that an adhesive is sprayed in 3DP (three-dimensional powder bonding technology and three-dimensional power bonding) printing. The viscoelastic damping device manufactured through the additive manufacturing technology has the advantages of being free of die machining, short in process, short in period forming, capable of saving materials and the like.
本发明涉及工程结构减振抗震和快速成型制造技术领域，公开了一种增材制造(3D打印)黏弹性阻尼装置，包括外侧约束钢板、中间钢板、高性能阻尼材料。阻尼材料共两层，对称布置于中间钢板两侧，内、外侧钢板设置于阻尼材料层外侧。其中，高性能阻尼材料为3D打印高分子聚合物，采用聚氨酯经FDM(即熔融沉积成型)进行挤出打印材料的方式制作；中间钢板与外侧钢板为增材制造钢板，采用钢粉体经LAM(即激光增材制造)制作而成。已分别制作完成的钢板和阻尼材料通过3DP(即3D粉末黏合技术，3D powder binding)打印中喷洒黏合剂的方式结合为阻尼装置整体。采用该种增材制造技术制作的黏弹性阻尼装置具有无模具加工、短流程、短周期成形、且节省材料等优点。
