Method for optimizing automobile sliding door opening and closing force based on test bed

Abstract

The invention discloses a method for optimizing automobile sliding door opening and closing force based on a test bed. According to the method, through the multifunctional sliding door test bed, according to the movement characteristics of a sliding door, a sliding door travelling wheel arm and guide rails are in contact at reasonable stress positions, the sliding door opening and closing force is optimized in the earlier stage of product research, and the door opening and closing force values are reduced to the greatest extent; during design, a certain angle relationship exists among the upper guide rail, the middle guide rail and the lower guide rail of the sliding door, due to manufacturing errors, the upper guide rail, the middle guide rail and the lower guide rail deviate from design values, and as a result, the opening and closing force becomes larger when the sliding door is opened and closed. By adjusting the test bed, the sliding door moves smoothly when being opened and closed, the door opening and closing force is reduced to the greatest extent so that the quality of the sliding door can be improved. Meanwhile, experimental verification of theories is conducted in the earlier stage of automobile design and development, the manufacturing cost of a body in white is reduced, a research method is provided for research and development of similar products, and research and development reference standards are provided.

Description

technical field [0001] The invention relates to a method for optimizing the opening and closing force of an automobile sliding door based on a test bench, and belongs to the technical field of automobile and vehicle manufacturing detection. Background technique [0002] Generally speaking, the opening and closing force of an automobile is divided into the unlocking force of the door handle and the opening force during the door opening and closing process. The present invention relates to the opening and closing force during the door opening and closing process. In the method of optimizing the opening and closing force of the automobile hinged door, it can be realized by optimizing the axis of the hinge, optimizing the structure of the limiter, and the like. [0003] For automobile sliding doors, the optimization of the opening and closing force can only obtain some empirical values ​​through continuous experiments. Many OEMs did not optimize the door opening and closing for...

AI Technical Summary

Problems solved by technology

Many OEMs did not optimize the door opening and closing force during the design process. They did not find that the door opening and closing force was too large or the door was not opened and closed smoothly until the model was rolled off the assembly line for testing or when the model was about to be launched. Generally, the only solution is to modify the moving parts. For example, increase the gap between the sliding door wheel arm roller and the guide rail, change to a better material for the wheel arm roller, or add lubricating oil to the kinematic pair, etc.

None of these methods are optimal for opening and closing force optimization of sliding doors
