Body in white module design method based on modularization product family platform

Abstract

The invention belongs to the field of structural design of body in white of vehicles, and relates to a body in white module design method based on a modularization product family platform. In a conception design stage of the body in white, on the premise that the vehicle body performance and the cost are comprehensively considered, a modularization thought of increasing the sharing degree of parts in a product family is introduced, by conducting feature-keeping optimization on codes in topological graphs corresponding to a structural assembly model, and conducting multilayer and multi-target optimization with the combination of a genetic algorithm, module sharing in the vehicle family of the vehicle models of the same level and even the vehicle models of different levels is guaranteed, on the premise that the vehicle body performance is guaranteed, the universal degree of the parts is increased, and the costs in various aspects are greatly reduced. According to the body in white module design method based on the modularization product family platform, a vehicle assembly design thought which is based on the modularization thought and in which the achievement of parts sharing is considered in the vehicle body conception design stage is provided for designers, the vehicle body assembly optimization design of the whole product family is achieved, and the method has very important practical significances in both the processes of vehicle body reverse improvement and forward design.

Description

technical field [0001] The invention relates to a method for dividing and screening body-in-white structure modules of cross-level vehicle models based on a modular product family platform used in the concept design stage, belonging to the technical field of body design, and mainly used for the whole series under the same product family at the initial stage of design. The body structure of the vehicle model is designed for module division and assembly method. Background technique [0002] With the year-by-year development of science and technology and the increasingly mature economic environment, world-class automobile manufacturers have begun to adopt a modular R&D model under the trend of global integration, thereby reducing the cost of production, manufacturing, maintenance and even material transportation, and shortening the cost of new models. At the same time, it can meet the diverse needs of different consumer groups and even different consumer individuals through cus...
