摘  要
 隨著國(guó)民經(jīng)濟(jì)的持續(xù)發(fā)展，人民生活水平的日益提高，道路交通網(wǎng)絡(luò)的不斷完善，汽車已經(jīng)成為人們生活中不可或缺的一部分，汽車數(shù)量的急劇增加給道路交通帶來(lái)了巨大的壓力，同時(shí)對(duì)汽車的安全性能帶來(lái)嚴(yán)峻的考驗(yàn)，人們?cè)谧非笫孢m度的同時(shí)對(duì)汽車的安全提出了更為嚴(yán)格的要求，同時(shí)由于汽車尾氣的排放給空氣帶來(lái)的污染已經(jīng)嚴(yán)重影響人們的健康，早在20世紀(jì)80年代，工業(yè)較為發(fā)達(dá)的西方國(guó)家就已經(jīng)開(kāi)始對(duì)汽車尾氣的排放標(biāo)準(zhǔn)做出了限制，并在近年來(lái)逐步提高了要求。為此，汽車制造商在開(kāi)發(fā)汽車產(chǎn)品是必須對(duì)其進(jìn)行嚴(yán)格的測(cè)試，而且很多實(shí)驗(yàn)必須在實(shí)驗(yàn)室內(nèi)完成，因而很多實(shí)驗(yàn)必須在實(shí)驗(yàn)室內(nèi)完成，因而對(duì)汽車環(huán)境實(shí)驗(yàn)艙提出了相應(yīng)的要求。
 汽車環(huán)境實(shí)驗(yàn)艙由圍護(hù)結(jié)構(gòu)、空調(diào)系統(tǒng)、新風(fēng)系統(tǒng)、光照系統(tǒng)、控制系統(tǒng)等部分組成。可以為輕型車整車部分進(jìn)行高溫適應(yīng)性試驗(yàn)、低溫啟動(dòng)及整車空調(diào)性能試驗(yàn)的要求。
 本文著重研究汽車環(huán)境實(shí)驗(yàn)艙艙體的設(shè)計(jì)，各個(gè)系統(tǒng)的布置及選用，可適用總質(zhì)量不超過(guò)3500kg的M1類、M2類、N1類點(diǎn)燃式發(fā)動(dòng)機(jī)，在試驗(yàn)時(shí)能提供-35℃～60℃的環(huán)境模擬條件，并能滿足發(fā)動(dòng)機(jī)排量3.0L，車速60km/h。可進(jìn)行的試驗(yàn)項(xiàng)目包括除霜除霧試驗(yàn)、加速試驗(yàn)、最大車速試驗(yàn)、滑行試驗(yàn)、最低穩(wěn)定車速試驗(yàn)、模擬爬坡試驗(yàn)、低溫駕駛適應(yīng)性試驗(yàn)、汽車采暖試驗(yàn)等。

 The design of the whole cabin and ventilation system in Automotive environmental test chamber
 Abstract
  In recent years, with the sustainable and fast development of Chinese economy, expressway, as the most important portion of the highway networks, had been developed at an astonishing fast speed, however which brought on increasingly severe ecological environmental problems in the mean time. The rapid increase in the number of cars brought great pressure to the road, while the safety performance of vehicles pose serious challenges, people in the pursuit of comfort, while the safety car made on the more stringent requirements. For this reason, when the car manufacturers develop its automotive products to rigorous testing, and many experiments must be completed in the laboratory, so a lot of experiments must be completed in the laboratory, which made the car environment, the corresponding requirements.
  The automotive environmental test chamber is made up of the envelope, air-conditioning system, air system, lighting system, control system components.It can provide high-temperature test, low temperature starting and vehicle air conditioning performance test for vehicle parts and light vehicles.
 This paper focuses on the design of automotive environmental test chamber, the layout and selection of each system.The test chamber is applicable to the total mass of not more than 3500kg of the M1 class, class M2, N1 type ignition engines. the test chanmber can provide -35 ℃ ~ 60 ℃ simulated conditions of the environment, and to meet the engine displacement 3.0L and 60km/h.It can do tests such as defrosting defogging test, acceleration test, the maximum test speed, glide test, the minimum steady speed test, simulation of climbing test, low temperature flexibility test drive, heating tests.
