摘  要
 随着国民经济的持续发展，人民生活水平的日益提高，道路交通网络的不断完善，汽车已经成为人们生活中不可或缺的一部分，汽车数量的急剧增加给道路交通带来了巨大的压力，同时对汽车的安全性能带来严峻的考验，人们在追求舒适度的同时对汽车的安全提出了更为严格的要求，同时由于汽车尾气的排放给空气带来的污染已经严重影响人们的健康，早在20世纪80年代，工业较为发达的西方国家就已经开始对汽车尾气的排放标准做出了限制，并在近年来逐步提高了要求。为此，汽车制造商在开发汽车产品是必须对其进行严格的测试，而且很多实验必须在实验室内完成，因而很多实验必须在实验室内完成，因而对汽车环境实验舱提出了相应的要求。
 汽车环境实验舱由围护结构、空调系统、新风系统、光照系统、控制系统等部分组成。可以为轻型车整车部分进行高温适应性试验、低温启动及整车空调性能试验的要求。
 本文着重研究汽车环境实验舱舱体的设计，各个系统的布置及选用，可适用总质量不超过3500kg的M1类、M2类、N1类点燃式发动机，在试验时能提供-35℃～60℃的环境模拟条件，并能满足发动机排量3.0L，车速60km/h。可进行的试验项目包括除霜除雾试验、加速试验、最大车速试验、滑行试验、最低稳定车速试验、模拟爬坡试验、低温驾驶适应性试验、汽车采暖试验等。

 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.
