Abstract

The invention discloses a wheel rim shape optimization method, which comprises the following steps of: establishing a rim equivalent section model and a finite element model by analyzing functional characteristics and working condition characteristics of a rim; extracting a force transmission path of the equivalent section of the rim by adopting a force transmission path visualization method; establishing a structural force transfer performance evaluation strategy, and giving an optimization strategy of the rim equivalent section force transfer performance; and designing a plurality of parameters to control the rim section shape, establishing a parameter optimization mathematical model, and conducting iterative optimization by adopting an optimization algorithm, so as to obtain a final rimshape and a hub model. According to the method, the force transmission performance of the rim structure is analyzed from the perspective of mechanics, suggestions for optimizing the section shape ofthe rim are given, a complex shape optimization mathematical model does not need to be established, and mechanical guidance can be provided for design and optimization of similar cylindrical thin-wallcomplex structures.

Description

technical field

[0001] The invention belongs to the field of lightweight design of automobile structures, in particular to a method for optimizing the shape of a wheel rim. Background technique

[0002] Lightweight is one of the important measures to achieve energy saving and emission reduction of automobiles. Wheels, as the main load-carrying parts in the driving system of the whole vehicle, are the most important A-level safety parts that affect the performance of the whole vehicle. It affects the smoothness, safety, braking and economy of the car.

[0003] The wheel hub is composed of rim, spoke and rim, which play the role of installing and supporting tires and axles. The rim is a typical ring thin-walled structure. There are tires installed on the outside, and enough space is left to install drive motors, brake lines and other components on the inside. There are many functional requirements and process restrictions. In addition, the rim also bears tires, Complex loads...
