Abstract: At present, China has become the world's largest single automobile production and sales market. The mainstream solution of passenger car body in white in the Chinese market is based on carbon steel punching and welding forming, and every passenger model from research and development to formal batch production be tested first to ensure that the structure and performance of the body in white solution meet the design requirements. The general assembly and integration process is one of the key processes in the body in white trial production process. Due to the fixed production of vehicle models, the conventional mass production line can not meet the needs of flexible and rapid switching production if it needs a lot of time and manpower to adjust the production model. Therefore, it is of great significance to study the passenger car body in white total assembly trial production line for the improvement of China's passenger car trial production and development capacity. Taking a carbon steel body in white total assembly production line as an example, the layout and application of this type of production line are analyzed and studied in detail.
