Therefore the security aerocyst took one kind of protective measure already was essential. I havemainly carried on the security aerocyst design work in this design,conducts the research to the security aerocyst work process, forcauses the crew member safety to design an appropriate securityaerocyst。 The auto safety aerocyst basic thought is: After has the first collision, Before second collision, Rapidly inserts in the crew member and between the automobile interior ponent to fill the gas the aerocyst, Let the crew member throw oneself on the aerocyst, absorbs crewmember39。 As a result of inertia function,On vehicle crew member to front movement, Thereupon has had in the vehicle in the crew member and the vehiclebetween the structural element second collision, In the accident creates the main reason which the crew member injures is the second collision。seffectiveness more and more to obtain the affirmation, Now the society also more and more is high to the security aerocystrequest。 關(guān)鍵詞:智能型安全氣囊、防護(hù)、安全傳感器、汽車碰撞。 故設(shè)計(jì)的主要工作是對(duì)氣囊電路中的 CPU、加速度傳感器的選擇、繼電器的選擇及與電路有關(guān)的器件,如為防止錯(cuò)點(diǎn)火而要設(shè)計(jì)一個(gè)點(diǎn)火電路、為防止信號(hào)干擾我們要加光隔離等一些措施。 介紹自行研制的智能式汽車安全氣袋控制系統(tǒng),該系統(tǒng)主要由單片機(jī)、傳感器、點(diǎn)火電路等組成,使用點(diǎn)火控制算法對(duì)汽車加速度信 號(hào)進(jìn)行判斷,輸出點(diǎn)火脈沖。 所以安全氣囊作為一種防護(hù)措施已經(jīng)是必不可少了。為了減輕和避免駕乘人員在第二次碰撞中受到傷害,乘員保護(hù)系統(tǒng)的設(shè)計(jì)目標(biāo)是在碰撞中利用約束系統(tǒng)(包括座椅、安全帶、安全氣囊等)避免或減緩乘員與車內(nèi)結(jié)構(gòu)件碰 撞造成的傷害。專 科生畢業(yè)設(shè)計(jì)(論文) 編號(hào) 畢業(yè)設(shè)計(jì) (論文 ) 汽車安全氣囊的應(yīng)用 Application of automobile airbag 院(系)名稱 專業(yè)名稱 學(xué)生姓名 學(xué)號(hào) 指導(dǎo)教師 2022 年 5 月 23 日 專 科生畢業(yè)設(shè)計(jì)(論文) 摘 要 汽車安全氣囊作為一種輔助的乘員 約束條件,在汽車發(fā)生碰撞時(shí)保護(hù)乘員的效用已越來越得到肯定,當(dāng)今社會(huì)對(duì)安全氣囊的要求也越來越高,尤其是對(duì)智能安全氣囊的需求也越來越廣泛, 當(dāng)汽車發(fā)生碰撞時(shí)汽車與汽車或汽車障礙物之間的碰撞稱為第一次碰撞,第一次碰撞導(dǎo)致了汽車速度的急劇變化。由于慣性的作用,車上的乘員向前運(yùn)動(dòng),于是發(fā)生了車內(nèi)乘員與車內(nèi)結(jié)構(gòu)件之間的第二次碰撞,事故中造成乘員傷害的主要原因就是第二次碰撞。汽車安全氣囊的基本思想是:在發(fā)生第一次碰撞后,第二次碰撞前,迅速在乘員和汽車內(nèi)部構(gòu)件之間插入一個(gè)充滿氣體的氣囊,讓乘員 “撲 ”在氣囊上,通過氣囊上的排氣節(jié)流阻力吸收乘員的動(dòng)能,使猛烈的第二次碰撞得以減緩,以達(dá)到保護(hù)乘員的目的。我在此設(shè)計(jì)中主要進(jìn)行了安全氣囊的設(shè)計(jì)工作,對(duì)安全氣囊的工作過程進(jìn)行研究,為使乘員安全而設(shè)計(jì)一個(gè)合適的安全氣囊。本系統(tǒng)具有體積小、可靠性高、抗干擾能力強(qiáng)、可進(jìn)行自診斷等特點(diǎn) 。所以我設(shè)計(jì)所做的主要工作就是對(duì)安全氣囊的硬件電路實(shí)行操作并對(duì)其的工作原理進(jìn)行分析,對(duì)其應(yīng)用進(jìn)行研究。 專 科生畢業(yè)設(shè)計(jì)(論文) Abstract The auto safety aerocyst took one kind of auxiliary crew memberrestrains the condition, Has the collision when the automobile protects crew member39。 Also more and more is in particular widespread to the intelligentsecurity aerocyst demand, When the automobile has the collision the automobile and theautomobile or between the automobile obstacle collision is called thefirst collision, The first collision has caused the automobile speed rapid change。 In order to reduce and avoids harnessing while the personnel receivesthe injury in the second collision, The crew protective system design goal is avoids or slows down the injury in the collision using the restraint system which in the crewmember and the vehicle the structural element collision creates。s kiic energy through the aerocyst on exhaust throttleresistance, enables the violent second collision to slow down,achieved protects crew member39。 The introduction independently develops the intelligent type autosafety air pocket control system, this system mainly by the mono
