Development and Implementation of Abnormal Noise Test System for Automotive Door Assembly Based on High and Low Temperature Environment

In the R&D and testing of vehicle door products, the assembly level abnormal noise OTS approval test is easier to ignore, so in the vehicle certification stage or after mass production and marketing, NVH quality problems such as door glass lifting abnormal noise occasionally occur, at this time, tracing quality problems forward often results in a large cost loss. At present, the resources for component level and vehicle level NVH testing and certification equipment on the market are relatively perfect, while the resources for assembly level NVH test equipment are less. Faced with this situation, this paper designs an automotive door assembly abnormal noise test equipment based on high and low temperature environment, the equipment can simulate the installation state of the real vehicle to the greatest extent, and has an upper computer and lower controller based on wireless architecture design, as well as a human-computer interaction system written based on LabView software. Good simulation, strong expandability, stable and reliable.
