Decontamination mechanism and experiment of navigation aid lamps based on adhesion dynamics modeling
In order to address the common pollutant removal problem on the light-emitting surface of embedded navigational aid lamps,a dry ice cleaning mechanism analysis method based on the adhesion kinetic model of pollutant particles and the sliding separation model of dry ice particles is proposed.By analyzing the adhesion kinetic model of different pollutants on the sur-face of light-emitting port lens,establishing the sliding separation model of pollutant particles,de-termining the critical separation speed of particle removal,and analyzing the velocity field distri-bution of dry ice particles through finite element,then studying the decontamination mechanism of different pollutants oriented to a specific pollutant and the influence of decontamination cleaning parameters on the cleaning effect,and on the basis of which,experimental verification was carried out.The experimental results show that setting different cleaning parameters to achieve the same cleaning effect of cleanliness,the dry ice consumption from removing dust is 0.01 L,the dry ice consumption from removing oil is 0.015 L,and the dry ice consumption from removing adhesive traces is 0.105 L.Under the premise of guaranteeing the cleaning effect,the cleaning parameters of different pollutants have been determined,which lays the foundation for the control of the actu-al dry ice automatic cleaning process.
