Research On Forest Fire Extinguishing Gun Buffering Device

Forest fire put out a small gun in today’s society is very effective forest fire extinguishingtools.Now use a large part of the forest fire gun for remote pneumatic gun fire. Air emissioncompared with gunpowder launch itself there is little pressure, the pressure drops rapidlywithin the bore and other shortcomings. Also the most important is that after the pneumaticgun fire resulting recoil makes shooting accuracy is reduced. Therefore, the impact ofreducing the recoil of the gun fire is one of the important means to improve the overallperformance of the pneumatic gun fire.The main content of this thesis is using air spring as the fire gun buffer model. This devicecan reduce the fire recoil gun is generated, can reduce the trip of gun recoil. Thisimprovement can make further fire guns range, more mobile and high speed. It can reducethe fire extinguishing gun tube to plate damage.In addition, buffer device is designed in thispaper can be matched with the mobile platform, to reduce the burden of fire fightingpersonnel.It can effectively improve the response speed of fire, reduce the preparatorywork time.The mobile platform is truck, it’s crawling ability and off-road ability are strong, itcan adapt to the mountains and forests and rugged terrain.Firstly, the existing home and abroad pneumatic gun fire cushioning device was initiallydescribed. According to the structural characteristics of the shortcomings of existing forestspneumatic gun fire and the common spring cushion machine, a novel spring buffersystem.The air spring buffer device is added without changing the existing fire extinguishinggun device. Use it to reduce recoil gun fire. Next, the working principle of this structure isdescribed and a detailed description of2D drawing part. Then, using Solid works to create a3D model of the structure.While initially established mathematical model gun fire. With the traditional spring cushion sleeve preliminary comparative analysis, the back seat of the law inboth cases.Then use ADMAS virtual prototyping technology in both cases the correspondingconstraints are added dynamics simulation analysis. From the results of simulation analysiscan know, less affected after the new spring cushion system improved cannon fire resultingrecoil of the gun rack. Finally, according to the law of launching artillery fire on the keycomponents by ANSYS finite element stress and strain analysis. According to the results ofthe analysis of the failure of components easily optimized and improved.Then again improvedcomponents of stress and strain analysis of the mechanical properties of componentsoptimized to verify whether the increase.
