Abstract

The invention belongs to the technical field of automobiles, and particularly relates to an anti-shaking design method for a passenger car outside rear-view mirror based on door closing impact load. The method comprises the following steps: step 1, modeling a vehicle door, a vehicle body and a rearview mirror, modeling a vehicle door sealing strip, modeling a vehicle door lock and modeling a vehicle door hinge; and step 2, designing impact jitter resistance of the outside rearview mirror according to the step 1. Structures of the vehicle door and the outside rear-view mirror are reasonably designed in the early development stage of the vehicle door and the rear-view mirror, the outside rear-view mirror can be prevented from shaking when the vehicle door is closed in the later stage, the development period is shortened, the research and development cost is reduced, the user sensory experience is improved, and the problem of outside rear-view mirror door closing shaking is solved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to an anti-vibration design method for an exterior rearview mirror of a passenger car based on a door closing impact load. Background technique [0002] In the development and trial production stage of passenger cars, it is often found that the exterior rearview mirror shakes obviously when the front door is closed. This problem affects the user's sensory experience, and greatly affects the user's overall evaluation of the vehicle and the establishment of a good brand image. [0003] In the past, the door-closing vibration problem of the exterior rearview mirror can only be reflected after the trial production. At this time, it will take a long time and high cost to optimize and modify the structure of the door and rearview mirror. [0004] In recent years, with the shortening of the development cycle of passenger cars, severe challenges have been posed to all aspects of develop...
