Abstract

The invention discloses a method for building a conceptual design model of a white automobile body. The method comprises the following steps: building conceptual models of corresponding structures of an upper automobile body by using a beam unit sequence, a plate shell unit and a rigid rod unit; building conceptual models of corresponding structures of lower automobile body by using the beam unit sequence, the plate shell unit and the rigid rod unit; building a conceptual model of a joint part by using a rigid rod unit and beam unit sequence connection mixing structure; building a conceptual model of a front coaming assembly by using topology optimization and topography optimization. According to the conceptual model which is built by the method for building the conceptual design model of the white automobile body, the corresponding rigidity and the corresponding stress distribution of the white automobile body can be more precisely simulated, and meanwhile, cross section and truncation databases are more easily constructed, and responses of the while automobile body to subsequent modifications on a cross section, a typical truncation, a model and the like can be reflected in more details.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method for establishing a conceptual design model of a body-in-white. Background technique [0002] The existing body-in-white conceptual model generally uses rod elements or beam elements to build the body-in-white frame, or only designs two-dimensional elements with thickness on the floor part to match the corresponding positions of the floor to establish the important sheet metal structure of the floor part, and then cooperates The joint part uses the beam element to establish the conceptual model of the body in white. Therefore, the existing body-in-white conceptual design model has large errors between the stress, displacement distribution and stiffness results calculated by the existing body-in-white conceptual design model and the completed body-in-white, and cannot truly reflect the physical properties and stress of the body-in-white. conduction. At the same time, the update o...
