Abstract: The purpose of this article is to study the compatibility and sensitivity of the flush door glass lifting system with the door sheet metal tolerances, as well as to explore the relationship between various input factors of the door sheet metal tolerances and the glass lifting torque and flushness difference, and the torque and flushness difference values under the limit tolerances. Based on the response surface analysis method in the design of experiment test design, the input factor values are adjusted and the corresponding output data are measured on the independently developed fixture, and the relationship between the relevant door sheet metal dimension factors and the glass lifting torque is analyzed. The conclusion is that in this system, the door cheat has smallest impact on the glass lifting torque, and the tolerance of the waistline opening has the greatest impact on the glass lifting torque. At the same time, the suitable sheet metal tolerance range for this system and the relationship between each input factor and output result are also verified, providing a theoretical basis for the development of subsequent similar structures.
