Design and development of a composite automotive anti-roll bar.

摘要

An analytical elasticity model is developed for laminated cylindrically anisotropic cylinders subjected to extension, bending, pressure, torsion, and transverse shearing. The model predicts the elastic response of thin or thick walled tubes as well as cylinders, and accounts for all elastic coupling present in the aforementioned loading cases. This model is incorporated into analysis software that predicts the linearelastic response of a composite automotive anti-roll bar. The user may input the bar's two-dimensional geometry, fibre-layup, diameter, and material properties. A filament-wound composite anti-roll bar is designed to act as a lightweight drop-in replacement for the high-performance steel anti-roll bar that is thoroughly benchmarked herein. A mass reduction of 63% is observed when comparing the structural composite bar design to the existing steel bar.
