Abstract

A program for automatically verifying safety regulations specified on the interior part of the automobile is developed. In the ECE regulation, any surface of the interior part is requested to have roundness larger than R3.2 where a sphere of diameter 165mm can collide. Our developed program initially generates points sufficiently covering the visible surface of the model. For each point, sphere-object intersections associated with the regulations are evaluated. If the surface portion around the point cannot satisfy the geometric condition of the regulation, red color is painted to the point. As the result, corner shapes of the CAD model with possibly injuring the driver and passenger in the car crash are extracted and displayed.
