abstract

One of major difficulties in developing and employing a concept model of a vehicle is to develop a simple and accurate model of joints. A vehicle joint is a subassembly formed by several members that intersect together. It is a thin-walled structure formed by overlapping metal sheets fastened by spot welds. The study of the joints has been important, because they can deform locally. This flexibility can affect noise, vibration and harshness (NVH) characteristics of a vehicle plus other structural performance characteristics under different loading conditions. The main difference between various kinds of concept models is the representation of body joints. Joints are important components of the auto body because they affect significantly, and in some cases, they even dominate, the static and dynamic behavior of a model. This paper introduces a new beam-like major compliant joint methodology. Joints are simulated with different parametric representations that present the major differences among various concept models. The development procedure of the beam-like major compliant joint is explained and the benefits of using this representation are discussed.
