Abstract
The utility model discloses a constrained damping vibration attenuation sheet structure which comprises a uniform-thickness damping layer, a uniform-thickness constrained layer shell and a vibration attenuated structure layer. The uniform-thickness constrained layer shell is adhered on the outer side of the damping layer, the vibration attenuated structure layer is adhered on the inner side of the damping layer, and the constrained layer shell comprises at least one uniform-section elongated reinforcing rib structure which is formed by means of local bending. The constrained damping vibration attenuation sheet structure has the advantage that the constrained layer of the constrained damping vibration attenuation sheet structure still can have rigidity which is identical to the rigidity of a constrained layer of an existing constrained damping vibration attenuation sheet structure or is even higher than the rigidity of the constrained layer of the existing constrained damping vibration attenuation sheet structure under the condition that the thickness of the constrained layer is reduced.
Description
Technical field
The utility model relates to damping vibration attenuation field, is specifically related to a kind of damping-constraining vibration-damping sheet structure.
Background technique
During solid vibration, make the energy method being dissipated in damping material as much as possible of solid vibration, be called damping vibration attenuation, a lot of mechanical components need to adopt damping-constraining vibration-damping sheet structure to reach the effect of good vibration and noise reducing when work.In damping-constraining vibration-damping sheet structure, restraint layer mainly plays effect of contraction to damping layer, to increase its shear deformation, so generally adopt the metal sheet of good rigidity, by increasing its thickness, further improve its rigidity simultaneously, but so, often can make again structure weight become heavy, expend more material.
Summary of the invention
The purpose of this utility model is to provide the lighter damping-constraining vibration-damping sheet structure of a kind of structure.
The technical solution of the utility model is: a kind of damping-constraining vibration-damping sheet structure, it comprises uniform thickness damping layer, stick to the uniform thickness restraint layer housing in damping layer outside and stick to damping layer inner side by vibration damping structure layer, this restraint layer housing comprises at least one prismatic long strip reinforcing rib structure being formed by local buckling.
Further, the flanging that above-mentioned long strip reinforcing rib structure is restraint layer housing edge.
Further, above-mentioned restraint layer housing is provided with the installation fixed hole being connected with long strip reinforcing rib structure.
Further, rigidity packing material is contained in the space forming between above-mentioned long strip reinforcing rib structure and damping layer.
Further, on above-mentioned long strip reinforcing rib structure, be also provided for folding up the next sinking ledge structure of rigid sheet that parallels stickup with damping layer.
The beneficial effects of the utility model are: the disclosed damping-constraining vibration-damping sheet of the utility model structure, by restraint layer housing is carried out to local buckling distortion, make it to form at least one prismatic long strip reinforcing rib structure, thereby make restraint layer in the situation that thickness reduces, still can reach equally even larger rigidity, reach the object that alleviates structure weight and save material.
Accompanying drawing explanation
Fig. 1 is a kind of sectional drawing of damping-constraining vibration-damping sheet structure.
Embodiment
Below by embodiment, by reference to the accompanying drawings the present invention is described in further detail.
The present embodiment discloses a kind of damping-constraining vibration-damping sheet structure, and as shown in Figure 1, it comprises damping layer 1, sticks to the restraint layer housing 2 in damping layer outside and sticks to the conduct of damping layer inner side by the motor car engine protecgulum 3 of vibration damping structure.Damping layer, restraint layer housing and by pressure sensitive adhesive, be bonded together between the motor car engine protecgulum of vibration damping, damping layer full wafer is rounded.At the edge of whole restraint layer housing, be provided with flanging 4, the cross section of flanging is L shaped, a long strip reinforcing rib structure 5 being formed by local buckling is also set in the middle of whole restraint layer housing, on long strip reinforcing rib structure, be also provided for folding up the sinking ledge structure 6 of the steel disc 7 isometric with long strip reinforcing rib structure, make the surface of contact between restraint layer housing and damping layer substantially keep smooth.The fixing threaded hole of two installation use is set in the flanging at restraint layer housing edge, by screw 8 further damping layer, restraint layer housing and be fixed together by the motor car engine protecgulum of vibration damping.
