“…Because of its simplicity and efficiency, the concept model has been extensively applied in vehicle design and analysis. Prater et al successfully developed methodology of concept modeling for vehicle structure and applied it for vehicle architecture assessment and optimization [1,2]. In the developed concept models, beam elements are used to model the components whose lengths significantly greater than the cross sectional area and subject to axial, bending, and torsion loads, such as pillars, rails, etc.…”

It is possible to use "architecture concept models" for CAE analyses supporting the design and optimization of a vehicle's general layout prior to the time-consuming and expensive preparation of detailed models. Suspension system, including kinematic linkages, compliance and damping elements, wheels, tires, and brakes, plays a key role in determining whether the basic layout of a vehicle is suitable for given application. This paper presents an appropriate set of architecture-level abstractions for suspension systems that can be incorporated into full-vehicle concept models. These modeling abstractions provide abstract representations of a wide variety of suspension system configurations that illustrate both geometric and functional properties without resorting to high-fidelity solid model renderings of parts using details that simply do not exist this early in the design process. The architecture concept suspension model presented in this study can be used for vehicles rigid body analysis.

“…Raasch and other people [3] built the simplified body model, which consisted of beam structure, joint element and large size shell element, rectangle beam was used to simulate the key beam structure, the intersection of two beam elements was connected by a joint element, the large size shell element represented the body sheet metal panels, mass was used to simulate other structure, parts were connected by rigid element. Ford [4] and other major automobile companies set up a simplified model of body which consisted of three parts of beam element, plate element and joint element.…”

A method of modeling method of the body using the simple structure surface is proposed. The structure surface model of half-integral pure electric car body is built. By transfer path analysis, it is known that structure surfaces are balanced in the bearing force, force transfer is consecutive, and the structure surface model is integrated. In addition, four force matrix equations respectively in the bending condition and in the torsional condition are derived, which are the basis of computing the simplified structure surface model.

“…of a concept BIW model, already in the early design phases. Some of the most widely used concept modelling methodologies are based on predecessor Finite Element (FE) models: a simplified structure layout of an existing vehicle FE model is created starting from the detailed model [1][2][3][4]. The result is a small-size and parameterized concept model, ready to be optimized.…”

A B S T R A C TIn the automotive field, size optimization procedures can be combined with concept modelling approaches, in order to design a vehicle Body-In-White (BIW) model with optimal static and dynamic performances already in the early design stages. However, this specific optimization problem, with hundreds of design variables, limited design space and often conflicting objectives, makes the choice of the appropriate optimization method really difficult. The aim of this paper is to show an industrial case study, where two different implementations of the classical gradient-based (GB) method are used in combination with a technique for vehicle body concept modelling to achieve a multi-objective BIW optimization of a passenger car.
