| The parametric design technology was applied to the field of automobile brake design, the method of the modernistic design of automobile brakes based on I-DEAS was put forward and the software system of Automobile Brake Parametric Design (ZDQCAD) was achieved in this dissertation. The main contents are included as following: the structure of all sorts of brakes was analyzed, some parts as the base parts to assemble different kinds of brakes were screened out, key parameters or attaching parameters of the parts and relationship between them were determined, then those parts were parameterized to establish a parametric model database based on I-DEAS; software interfaces and interfaces statements were designed by Visual Basic; strength distribution of key parts was optimized by I-DEAS.In this ZDQCAD software system, structure style of brake was defined and structure parameters of parts were input according to the design desires and three-dimensions solid model of the parts were displayed by transferring the parametric models in parametric model database; the whole computer aided process of automobile brake design was realized such as selecting brake style, deciding structure parameters, selecting parts, deciding parameters of parts, checking computations of performance and drawing three-dimensions solid model; a good platform to improve the design of automobile brake was provided at last. |
