Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: a kind of compound magnetic damping sheet, including damping sheet 1,
The quantity of damping sheet 1 is two, and connection is pressed at the outer between two damping sheets 1, and the inside between two damping sheets 1
Internal cavity 4 is formed, is equipped with corrugated plating 5 in internal cavity 4, and inner sidewall of the corrugated plating 5 successively with two damping sheets 1 is connected and fixed,
Damping sheet 1 is mainly made of damping layer a6, damping layer b7, rust-proof coating 8 and sound absorbing layer 9, between damping layer a6 and damping layer b7
It is press-fitted together as one, the lateral wall of damping layer a6 is coated with rust-proof coating 8, and the lateral wall of damping layer b7 is coated with sound absorbing layer 9.
In the present embodiment, the ratio of magnetic product is optimized by the combination of Specific gravity damping material and magnetically damped material
Weight (density), is substantially reduced magnetic product specific gravity (density), reduces complete vehicle weight, indirectly realizes energy saving purpose, and hinder
Buddhist nun layer a6 and damping layer b7 double-layer structure change this product antivibration attenuation curve, under the premise of guaranteeing that magnetic attraction is constant, resistance
Buddhist nun's coefficient promotes 20% in original basis, internal cavity 4 is formed by the inside between two damping sheets 1, so as to effective
Sound source is isolated, improves soundproof effect, and the setting of corrugated plating 5 improves the protection intensity of double layer damping plate 1, so that
Car body integral strength increases, and the antirust ability of damping sheet 1 can be improved in the setting of rust-proof coating 8, and the setting of sound absorbing layer 9 can be right
