Front wheel envelope generation method and device, computer storage medium and equipment

Abstract

The embodiment of the invention discloses a front wheel envelope generation method and device, a computer storage medium and equipment, and is used for improving the envelope analysis precision. The method provided by the embodiment of the invention comprises the following steps: receiving input limit range data of front wheel bounce and limit range data of front wheel steering, wherein the limitrange data of front wheel bounce is expressed in the range of the position of a geometric center point of a front wheel, wherein the limit range data of front wheel steering is represented by the position of any fixed point on the central axis of the front wheel; outputting a first coordinate value set of a front wheel center point and a second coordinate value set of a fixed point on a front wheel central axis according to the limit range data of front wheel jumping and the limit range data of front wheel steering; obtaining outline data of a front wheel tire; and generating a front wheel tire envelope according to the outline data, the first coordinate value set and the second coordinate value set. According to the embodiment of the invention, the envelope analysis precision can be improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a generation method, a generation device, a computer storage medium and equipment of a front tire envelope. Background technique [0002] The tire envelope is the space occupied by the wheel as it bounces up and down and turns to its limits. The tire envelope can be used to check the motion interference between the wheel and the surrounding subsystems, and at the same time affect the design changes of the subsystems, such as the stabilizer bar, frame, etc.; in the early design stage, the tire motion envelope also affects the wheel structure development of the vehicle. Distance, the minimum turning diameter of the vehicle and other parameters. Therefore, in the early development stage of the vehicle project, accurate calculation and analysis of the tire motion envelope has a certain role and significance. [0003] The current method of generating the tire envelope surface in...

AI Technical Summary

Problems solved by technology

[0003] The current method of generating the tire envelope surface in the automotive industry uses motion simulation software to generate the envelope surface of the motion trajectory. There are 10 combined working conditions such as half-load, full-load, suspension tension, suspension compression, left turn limit, right turn limit, etc. Through the simulation of the working conditions, different attitudes are output according to different working conditions, and the attitude includes the beating of the wheels And the steering of the wheel, the envelope surface is generated according to the output attitude, the analysis conditions are insufficient, and the number of output attitudes is small, resulting in a relatively rough motion envelope and low analysis accuracy
