It includes that it overlaps I and 2 shock absorber II of 1 shock absorber of establishing respectively to vibrate the different positions of section of thick bamboo urceolus wall at the sensor, and shock absorber I is damping rubber with II main parts of shock absorber, and damping rubber bottom embeds has the mounting nut who is used for the sensor installation, forms damping and installation integral structure. The utility model discloses possess the shock absorber of installation and damping function simultaneously, can regard as product damping annex to form a complete set in the product for it is more convenient that the user uses, has improved the resistance to shock of product simultaneously.
Description
Technical field
The utility model belongs to the technical field of vibration cylinder pressure transducer vibration damping, is specifically related to a kind of damper mechanism for vibration cylinder pressure transducer, can be used for the pressure measxurement of airborne miniaturization air data system and Ground Meteorological, pressure checking is measured.
Background technology
Vibration cylinder pressure transducer is the sensor based on resonant mode measuring principle, because its vibrating barrel adopting is single-ended clamped cantilever design, make this series products have certain sensitiveness to ambient vibration, while using sensor under the environment that user has relatively high expectations at vibration level, need to take vibration reducing measure, common each user's using method differs, one method is to reach effectiveness in vibration suppression according to its mounting structure at its outer wrap vibration damping sponge or sponge rubber etc., a kind of method is to be inserted in rubber in the fixing part in vibration cylindrical shell two ends, rubber packs part into, secure it to again mounting base, mounting base increases secondary shock absorber in the time installing with next stage base plate again. such scheme increases shared sensor volume virtually, makes user need in use additionally to consider that vibration damping installation just can be used, and makes troubles to user.
Summary of the invention
The utility model is not with shock absorber in order to solve vibration cylinder pressure transducer self, vibration resistance is poor while installing and using, and the oscillation damping method of existing vibration cylinder pressure transducer increases the shared volume of sensor, use the problem of making troubles to user, a kind of damper mechanism for vibration cylinder pressure transducer is provided.
The utility model adopts following technical scheme to realize:
A kind of damper mechanism for vibration cylinder pressure transducer, be included in sheathed 1 shock absorber I and 2 the shock absorber II of sensor vibrating barrel outer tube wall diverse location difference, shock absorber I is arranged on the tip position of sensor, with the mating holes of sensor be blind hole structure, sensor is played to axial retention effect, shock absorber I top is provided with two projections, and for the location of circuit board assemblies one end of sensor, the circuit board assemblies other end is arranged on the vibrating barrel assembly of sensor, the mating holes of shock absorber II and sensor adopts through-hole structure, the air pressure that is inserted in sensor connects mouth end, the cylinder base assembly profile that connects the sensor that mouth is connected with air pressure is square shape, the Quad Sides length of tubular assembly is more than or equal to the mating holes aperture of shock absorber II and sensor, shock absorber II is played to axial retention effect, it is middle near sensor cylinder base assembly and vibrating barrel assembly link position that another one shock absorber II is installed on vibrating barrel, shock absorber I and shock absorber II main body are vibration isolation rubber, vibration isolation rubber bottom is built-in with the mounting nuts for installation of sensors, form vibration damping and integral structure is installed.
Existing vibration cylinder pressure transducer, uses and brings very big inconvenience to user, and user adopts vibration reducing measure in use voluntarily, under the prerequisite of not understanding sensor construction mechanism, can not effectivelyly reach effectiveness in vibration suppression. The utility model has the design feature of single-ended clamped cantilever in conjunction with the vibrating barrel of its inside, choose sensor vibration performance is affected to little vibration damping location point, the damping property that utilizes rubber can absorb vibration transmission has designed a kind of shock absorber that simultaneously possesses installation and vibration-damping function, can be used as product vibration damping annex and be matched in product, user is used more convenient, improved the resistance to shock of product simultaneously.
The utlity model has following beneficial effect: 9mm vibration cylinder pressure transducer is a kind of product of miniaturization on existing product basis. As shown in table 1,9mm vibration cylinder pressure transducer is compared with existing 18mm vibration cylinder pressure transducer, and volume weight all reduces to some extent. 9mm vibration cylinder pressure transducer increases after vibration reducing measure, and volume and weight slightly increases, but sensor resistance to shock obviously improves. Resistance to shock empirical tests, at power spectral density 0.032g2When/Hz, sensor vibration error 0.01%FS, can meet existing airborne products instructions for use. The comparable situation of the utility model and existing structure is in table 1.
