Abstract

According to a tire digital design method based on generalized parameterization, full-cycle product design is implemented based on generalized parameterization, and on the basis of a product geometricmodel of variable parameters, a parameter sequence is driven to change under engineering constraints, so that model updating of different levels and granularities is realized. The tire digital designmethod realizes a novel tire digital management model and a design method through digital management of different forms, different parameters and different characteristics. The tire digital management model comprises geometric parameter information and non-geometric parameter information of a product, and mainly comprises the following four layers of models: a size characteristic parameter digital model, a theoretical performance parameter digital model, a part parameter digital model and a machining process parameter digital model.

Description

technical field [0001] The invention relates to a tire digital design method based on generalized parameterization, which covers the whole design cycle of tire structure, formula and manufacturing process, and belongs to the fields of mechanical manufacturing and computer information. Background technique [0002] In the field of tire design and manufacturing, product parametric design is generally based on two-dimensional or three-dimensional software. The essence of the parametric method is a constraint-based product description method. In the entire design process, a product with a set of parameters is obtained through constraint specification, constraint transformation solving process, and constraint evaluation process. Parametric research can be traced back to the 1960s. In the Sketchpad system developed by Sutherland, for the first time, geometric constraints were expressed as nonlinear equations to determine the position of two-dimensional geometric objects. Most of ...
