Technical field
The present invention relates to sensor field, in particular to it is a kind of can repeat impact stress monitoring sensor.
Background technique
Currently, utilizing the piezoelectric film sensor of (PVDF, poly (vinylidene Fluoride)) Piezoelectric Film for Designing
It is mainly pasted onto the surface of the structure of test, test structure is caused structural vibration response by impact, but when PVDF piezoelectricity passes
Sensor is pasted at institute's geodesic structure shock point, when can not resist repeat impact effect, so that punching effectively cannot be measured accurately
A stress value at hitting.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide it is a kind of can repeat impact stress monitoring sensor,
Specific technical solution is as follows:
It is a kind of can repeat impact stress monitoring sensor, including shell up-protective layer, shell lower protective layer, epoxy resin

It is described that shell up-protective layer and shell lower protective layer are bonded together by epoxide-resin glue, PVDF piezoelectricity is thin
Film sealing；
The conducting wire is drawn out of shell, is connected respectively at PVDF piezoelectric membrane positive and negative anodes.
It is described it is a kind of can repeat impact stress monitoring sensor, preferred embodiment is the shell up-protective layer and shell
Body lower protective layer is steel.
It is described it is a kind of can repeat impact stress monitoring sensor, preferred embodiment is that the PVDF piezoelectric membrane is adopted
LDT0-028K model is produced with Jing Liang company of the U.S..
It is described it is a kind of can repeat impact stress monitoring sensor, preferred embodiment is that the black insulating layer is adjusting
Grease is constituted.
Beneficial effects of the present invention: wrapping up PVDF piezoelectric membrane using two-sided steel plate protective layer, constitutes repeat impact monitoring
Sensor, and encapsulated with epoxy glue layer, and use two-sided steel plate shell, wherein a piece of plane steel plate shell, another is
Have reeded steel plate shell, and PVDF piezoelectric membrane is placed wherein, another plate plane steel plate shell is covered on PVDF piezoelectricity
Film surface is pasted together using epoxide-resin glue between most latter two steel plate shell.Treated in this way repeatedly
Impact stress monitoring sensor can be affixed directly to institute's geodesic structure or component surface, and will not make the biography because of repeat impact
The inside of sensor is impaired, this sensor shock signal has sensitive monitoring and the high property of accuracy, can also be embedded to structure or
Component inside monitoring of structures or component inside impact load stress value.The invention patent can be pasted at surveyed shock point, with
Just the impact load stress value for the structural elements that is hit is obtained；The utility model patent can effectively obtain repeat impact effect
The impact stress numerical value of flowering structure or component, according to surveyed impact stress numerical value, data can be to the structure under the percussion
Or one-to-one relationship is established in component repeat impact stress and response.Percussion can cause the large deformation of structure or component,
The invention patent can measure each impact stress value of structure or component under repeat impact effect, and according to impact stress value
