Damping vibration attenuation structure oriented to high-temperature environment and topological optimization method

The invention relates to the technical field of vibration and noise reduction, in particular to a high-temperature-environment-oriented vibration reduction structure with damping and a topological optimization method. The high-temperature-environment-oriented vibration reduction structure is laid on the surface of the vibration reduction structure and is composed of a metal material, a damping material and a heat insulation felt; the damping material is manufactured in a casting mode, the bottom and the side faces of the damping material are wrapped by the heat insulation felt so that it can be guaranteed that the damping material is not melted at the high temperature, and the bottom of the damping material is borne by the metal material. Based on the damping vibration attenuation structure, the metal material, the damping material and the heat insulation felt are subjected to topological optimization design by taking optimization vibration attenuation as a target in a high-temperature environment; the vibrat
