Abstract

The invention discloses a design method for solving the problem of inconsistent highlight of a vehicle body profile. The method comprises the following steps: finding out main modeling characteristicsof a front side view of a vehicle body; finding out main modeling characteristics of the front view of the vehicle body; finding out transition characteristics between two views of the vehicle body;analyzing the highlight trend of the main modeling features from a front side view; analyzing the highlight trend of the main modeling features from the front view; profile highlight conditions corresponding to a front view and a front side view of a light source are respectively checked from X, Y and Z directions of vehicle body coordinates, highlight is required to be consistent with a characteristic line trend, highlight radian is full, highlight convex and concave dimensions are taken as judgment standards, convex and concave fluctuation cannot occur, only single convex and single concavedistribution and uniform highlight density can occur. Highlight among components is smooth without sudden change. According to the invention, profile deviation caused by profile highlight adjustment is very small, and the change of the internal structure of a part and the change of engineering arrangement and structure cannot be caused.

Description

technical field

[0001] The invention belongs to the technical field of car body appearance, and in particular relates to a design method for solving the inconsistency of highlights on the profile of a car body. Background technique

[0002] The following aspects are generally required for profile highlight evaluation and control: (1) In the initial stage of surface A, the highlight trend of the basic profile of the car body should be planned, that is, the highlight trend of the profile (A surface) tends to be consistent with the shape characteristic line (2) For the relationship between the highlight trend of the profile and the corresponding control points, it is required to form a design specification for the change of light and shadow, the number and arrangement of the control points, and the direction of movement; (3) The deviation of the profile due to the adjustment of the highlight It is required to avoid changing the internal structure due to large surface changes wi...
