The stabilizer bar plays an important role in the automotive vehicle, especially in traction and braking condition. Stabilizer bars (also known as Traction bar, Sway bars or Anti-roll bars) are used to stabilize a vehicles from excessive chassis roll when the vehicle running in high traction conditions. Stabilizer bars are generally used on smooth traction conditions. Anti-roll bars improve cornering behavior by reducing body roll.The aim of the project is to replace “Forged Solid stabilizer rod by using High strength Tubular stabilizer bar” there by reducing the weight of the product and increase the fuel efficiency of the vehicle. The project involves theoretical estimation of torsional stress in the stabilizer bar and validate with finite element analysis and experimental results.
