Design and Optimization of the Mudguard Bracket with Respect to Transmitted Vibrations

Abstract

A vehicle suspension system is subjected to random vibrations, excited by the driving conditions and transmitted from wheels to accessories and individual parts attached to the vehicle’s frame. This thesis deals with the response of the prototype mudguard brackets, which were breaking in real service. In order to solve this issue, vibration measurements were conducted using sensors mounted on the vehicle’s frame, reading random excitations from normal vehicle operational conditions. These data were processed, for simulating the excitations of the natural frequencies of the mudguard brackets and to find out the maximum stresses caused due to random vibrations in various speeds, causing the part to fail and break. The Target goal is lowering the maximum stresses, by redesigning and adjusting the original bracket design to endure the random vibrations in real operational conditions
