Sliding door guide rail arrangement method and system

Abstract

The invention discloses a sliding door guide rail arrangement method and system. The sliding door guide rail arrangement method comprises the following steps: obtaining primary arrangement meeting kinematics feasibility verification analysis; converting the primary layout into an early-stage scheme rack; the early-stage scheme rack is utilized; verifying whether the use parameters of the early-stage scheme rack of the primary layout comprising the three guide rails meet the requirements or not; the early-stage scheme rack meeting the requirements is used as a final guide rail arrangement scheme; finally, according to the final guide rail arrangement scheme; establishing a kinetic analysis model, and simulating and correcting the final guide rail arrangement scheme by utilizing the kineticanalysis model. Therefore, the purpose of verifying the use parameters of the determined final guide rail arrangement scheme before actual vehicle manufacturing is achieved, the design risk of the sliding door is reduced, the situation of repeated modification in the actual vehicle manufacturing process is avoided, the development and verification cost of the sliding door is reduced, and the development period of a sliding door project is shortened.

Description

technical field [0001] The present application relates to the technical field of vehicle engineering, and more specifically, to a sliding door guide rail arrangement method and system. Background technique [0002] The sliding door refers to the door that mainly moves in the direction parallel to the side of the motor vehicle body during the door opening and closing process. The sliding door has the advantage of not occupying a large outside area of ​​the vehicle after opening, and can better avoid the door from being opened outwards. Possible collisions with pedestrians. [0003] In the development process of the sliding door, how to balance the arrangement angle and spatial position relationship of the upper, middle and lower guide rails of the sliding door is a major problem that plagues those skilled in the art. Whether the arrangement of the upper, middle and lower guide rails of the sliding door is reasonable directly affects the kinematics and dynamics of the sliding...

AI Technical Summary

Problems solved by technology

The current sliding door guide rail layout method is to first use CATIA software to analyze the kinematics of the three guide rails arranged in the previous stage, and then directly apply the guide rail layout scheme that satisfies the kinematic analysis to the actual car manufacturing process, and then only use soft film to build cars and Slam and other actual tests to further verify whether the guide rail layout of the sliding door meets the requirements in the early stage, resulting in a high risk in the design of the sliding door, which needs to be revised repeatedly in the actual car manufacturing process, thus making the development and verification of the sliding door costly and difficult for project development. Long cycle issues that may even affect the original molding style or design that would overturn the sliding door
