“…These findings are consistent with previously conducted studies on joint modelling (i.e. [17,22]). The discrepancy in the results presented in Figure 14 is due to the joint modelling technique available in VCS (connection of intersecting beams to their geometrical centre), which does not provide adequate response prediction in case of out-ofplane deformation.…”

Very fast full vehicle simulations through the use of effective, but drastically simplified digital models is a topic of great interest to automotive manufacturers and research communities. A nonconventional modelling and simulation approach using the macro-element methodology, embedded in Visual Crash Studio (VCS), is assessed. Modelling practices for converting finite element models to macro-element models are developed and presented. A large number of automotive systems, ranging from components and sub-systems to full vehicle models, is investigated. Numerical results obtained from VCS and the finite element code LS-DYNA compared moderately in the majority of the cases. The accuracy and efficiency of the macro-element methodology for vehicle crashworthiness analysis as well as the necessity for model corrections are discussed. Through improved functionality and accuracy, the macro-element methodology could potentially enable engineers to evaluate multiple conceptual designs in shorter times and revolutionise the vehicle development phase.

“…A numerical method is presented to take into account the deformation of the joint connections in linear, non-linear and stability analyses of threedimensional thin walled beam structure. Moon et al [7] presented a joint modelling methodology where the definition and assumptions of the joint are discussed. In addition, the joint stiffness analytical model is proposed using static load test results and also presented the sensitivity analysis method and a joint stiffness-updating algorithm.…”

The paper discusses the knowledge on the behaviour of T-frame under specific loading will be obtained by experimental methods in order to investigate the deflection of the vehicle B-pillar or T-frame. In addition, a series of T-frame were designed with inner diaphragm at various location in the sill member in order to investigate the effect of inner diaphragm and noncontinuous closed hat section in the sill member. Lastly, the results from the experimental tests were compared with the finite element analsysis results to demonstrate the effectiveness of the inner diaphragm in the automotive B-pillar.

“…Fredricson [2] proposed the concept of 2-joint and established a simplified model which was used in automotive structures. And some researchers modeled some simplified models with springs and beams to describe the flexibility of the joints which are suitable for the design process such as Nikolaidis [3] and Moon [4]. This paper uses GuYan condensed method [5] 2) Setup of twisting working condition: The torsion stiffness is distributed along the longitudinal of the car body.…”

The joint characteristics should be determined in the early stage of a car body design. In this study, the joint characteristics of a car body were expressed through the GuVan condensed model. The condensed joint model was applied to A-pillar upper joint of car body. In addition, it was applied to the car-body simplified model with beams and GuVan condensed joints (Model II). And we established the car-body simplified model with beams and detailed joints (Model I). It confirms the exactitude and effectiveness of this method through the results of static analysis and modal analysis of the two models.
