Description
Technical field
The utility model relates to a kind of damping block, relates in particular to a kind of conductive vehicle vibration damping plate.
Background technology
At present, known vehicle vibration damping plate generally is made up of three ply board, i.e. upper strata one deck steel plate, the nonconducting viscoplasticity resin material layer of middle one deck, lower floor's one deck steel plate.The nonconducting viscoplasticity resin material layer of middle one deck bonds together the steel plate on both sides about it, forms a damping block.The purpose that adopts damping block is exactly to reduce the vibration of vehicle structure part.
The principle of damping block vibration damping: vibrate by bending and make viscoplasticity resin material layer when elongation when frame for movement, the steel plate of levels stops the elongation of viscoplasticity resin material layer; On the contrary, when the viscoplasticity resin material layer produced compression with the vibrational structure flexural vibrations, the steel plate of levels stoped its compression again, made inner shear strain and the stress of producing of viscoplasticity resin material layer.And shear strain and stress can make viscoplasticity resin material consume more energy, have reduced the vibration of steel plate.But this steel plate structure is unfavorable for the spot welding of auto parts.
The principle of spot welding is: two metal weldments are assembled into lap joint and are pressed on up and down between two electrode tips; Through big electric current, this electric current forms resistance heat between the weldment contact-making surface in power-on and power-off cartridge, weldment, resistance heat fusing weldment metal; Form solder joint, realize welding.Existing damping block makes when carrying out damping block spot welding, to be insulated between the upper and lower electrode tip that electric current can't pass through, thereby can not have a resistance heat owing in the middle of damping block, be the nonconducting viscoplasticity resin material layer of one deck.And resistance heat is the primary condition that realizes spot welding, lacks this primary condition damping block and can't realize welding, and this has also restricted the application of damping block on automobile.
Like Chinese invention patent notification number: CN100351074C; Open day: the patent of invention on April 19th, 2006 disclosed a kind of steel cellular sandwich vibration damping plate inuse for cars and preparation method thereof, belongs to the structure function field of materials, and its cellular sandwich composite plate is the panel material strong by two layers of thin; Therebetween one layer thickness is that the comb core of 5～8 times of plate thicknesses is formed; Comb core adopts the method processing of punching press, and its preparation method is an inserts in the middle of between panel material and comb core, putting into, and treats that with three layers composite is heated to the melt temperature of middle inserts; Be incubated 2～4 minutes, inserts is fully melted; Get into then and realize 10%～15% distortion in the milling train, the steel plate after compound carries out diffusion annealing, reaches the compound requirement of transient liquid phase, makes between panel and core through the diffusion generation isothermal solidification of atom, and formative tissue connects the surface uniformly.But the cellular sandwich composite plate complex manufacturing technology of this structure mid portion, cost is higher, and because comb core adopts metallic composite to process, and damping property is not good, is not easy to extensive use in batches.
