Abstract: There are two distinct Finite Element model classes supporting vehicle body design. The familiar detailed model, achieving accuracy by precisely simulating geometry and assembly interfaces, is useful for conducting trade-off studies after detail drawings become available. Architecture concept models, representing structural behaviour from major load-carrying members and joint layout, are valuable for early vehicle development design direction studies. This paper presents a generic vehicle body concept modelling process and compares three joint model representations. Joint representation limitations are discussed, and the joint methods| NVH results are compared with those from a detailed model. The conclusions are applicable to other structures of similar nature.
