Abstract

The invention provides an interference checking method and system for a dynamic enveloping surface of a tire. The interference checking method comprises: determining the dynamic enveloping surface of the tire; according to a defined checking range, only activating parts model data in the checking range from full vehicle model data; and performing interference checking on the dynamic enveloping surface of the tire and the parts model data activated in the checking range. According to the interference checking method and system, the calculation amount can be reduced, and the computational efficiency can be improved.

Description

technical field [0001] The invention relates to a tire dynamic envelope surface interference inspection method and system. Background technique [0002] In the process of automobile design, the inspection of tire dynamic envelope interference is an important work. Wherein, the tire dynamic envelope surface refers to the envelope surface formed during the dynamic movement of the tire, and the envelope surface formed by the space occupied by the tire when it jumps up and down and turns to the limit position. The dynamic envelope surface of the tire determines the opening shape of parts such as wheel housings and fenders. The tire dynamic envelope surface interference check is to check whether there is motion interference between the tire and the lateral stabilizer bar, frame, and surrounding body parts according to the tire dynamic envelope surface. [0003] In the prior art, in the process of checking the tire dynamic envelope surface interference, it is often necessary to ...
