Introduction for the Test Ability of Automotive CWT

Environmental adaptability test is an essential link in the vehicle development and verification process. CWT has become an important facility for environmental adaptability development and verification. CWT can simulate various environmental conditions of vehicles driving on the road, including temperature, humidity, solar, airflow, driving resistance, rain, snow, road thermal radiation, etc., to realize the vehicle environmental adaptability test without being restricted by seasons, regions and time. The test conditions of the CWT are easy to control and have good repeatability, which can improve the efficiency and accuracy of vehicle environmental adaptability development and verification, which can greatly shorten the development cycle of vehicles and reduce development costs. It is of great significance to the research and development of complete vehicles and parts. This paper introduces the basic structure, functions, test models, and test items that can be carried out in the CWT. It focuses on extreme climate performance simulation test of the automobile that can be completed by relying on the CWT, and combines the current industry status to summarize the use and development of the CWT.
