Production and manufacturing, for example, brake, clutch and piston contact, the combination pressure of liquid crystal display panel, tire and crawler belt
The Winding pressure etc. of support pressure, high-performance film and paper measures and accurate machinery is arranged and adjustment aspect.It is answered
It is with principle：When being under pressure, minitype particle rupture, color-producing bodies react to each other with substance that show color, occur on film red
Area, and color density changes with the change of stress level, is ruptured at various pressures by adjusting microparticle, so that it may it obtains
Obtain the pressure value within the scope of extensive pressure.
Currently, the method for detection flatness is relatively more, such as the roughness measurement method based on Kalman filtering, that is, pass through
The optimal estimation value that the vibration displacement of planeness measuring apparatus is obtained using Kalman filtering system, to realize the vibration displacement
Optimal estimation value reduces the error of flatness result of calculation closest to true vibration displacement.But these devices are usually used

Flatness is assessed by the otherness of the contact resistance on Detection electrode surface, but since detection position is limited, Bu Nengzhun
Really reflect the flatness of entire pole plate, and because stacking pressure is small, cannot really reflect smooth under pile actual assembled power
Degree.
The patent that notification number is CN202361941U is proposed using carbon paper dummy electrode (by two carbon paper and a white stick
Paper forms) method carry out the flatness of Detection electrode, i.e., actual assembled pressure is applied to the pile for being added to carbon paper dummy electrode,
Heap is torn in pressurize open afterwards for a period of time, by the clarity and range of mark on the white stick paper of observation come the flatness of Detection electrode, still
Due to needing to make carbon paper dummy electrode by oneself, takes and lengthen, and be difficult to ensure the consistency and flatness requirement of preparation process, to it
The accuracy of the flatness of measuring pad has an impact afterwards.
