Description
Technical field
It is more particularly to a kind of to be rung based on simulated humanbody mechanics the invention belongs to police anti-riot Ordnance Protection measures of effectiveness field
The method that quantification test and evaluation should be carried out to the protective benefitses of Antiriot dress.
Background technology
Antiriot dress is the individual protective equipment for designing, producing for public security spy patrol police, riot police, People's Armed Police, it is desirable to is had
Protecting against shock, anti-lancination and certain fire resistance, to reach by the purpose that oneself injury is reduced when attacking.Therefore, to anti-riot
The evaluation of protective benefitses is taken, in addition to the technical indicator of Antiriot dress in itself, it is anti-riot should also to pay close attention to protection aftereffect-wear
Take personnel it is under attack when the order of severity that whether comes to harm and may come to harm.Because Antiriot dress is by different energy
Deformation, and then the crushing failure at high speed wall of the chest in various degree is produced when measuring external impacts, wall of the chest deformation and percussive pressure Reeb can be caused to exist
Transmitted in breast tissue and organ, whether personnel sustain damage depending on wall of the chest deformation velocity and deflection.Send out within 2008 in China
Cloth and the People's Republic of China (PRC) industry standards of public safety GA 420-2008 implemented《Police Antiriot dress》Deformed for Antiriot dress
Technical requirements and test method be to lie against the shirtfront of Antiriot dress, back parts on standard clay respectively, with 100J energy
20mm is not to be exceeded in impact, clay depth of cup.But this method and standard are remained in many deficiencies, following three are mainly reflected in
Individual aspect：
1st, test model is unreasonable.GA 420-2008《Police Antiriot dress》The survey deformed using standard clay as the wall of the chest
Die trial type.This standard clay is size for 600mm × 600mm × 150mm, physical characteristic and soft tissue is close, single density
Uniform dielectric.And human chest is that how close the geometry that soft tissue by density and varying physical characteristics and bone are formed is irregular
Spend complex dielectrics.Therefore, the test model deformed as the wall of the chest by the use of structure, density and physical characteristic and the totally different clay of human body is not
It is reasonable to the greatest extent.
2nd, reflect that wall of the chest deformation process is not comprehensive.GA 420-2008《Police Antiriot dress》Chest is reflected with clay cup depth
Wall maximum instantaneous deflection, but wall of the chest deformation velocity can not be reflected.
3rd, evaluation criterion is not objective.GA 420-2008《Police Antiriot dress》Regulation is with 100J energy impact Antiriot dresses, backing
20mm is not to be exceeded in clay depth of cup.Substantial amounts of biologic test research shows, even if Antiriot dress reaches 100J energy impacts
Clay depth of cup is no more than 20mm technical requirements, still can not avoid damage to occur completely, as skin soft tissue degree is frustrated
Wound, the heart, empsyxis.
