Headlamps are playing an important role in the design of a vehicle. Design and development of automotive headlamp in a systematic manner by considering post failures can avoid as much as modification costs and rejection costs as possible and can meet customer requirements. The headlamp assembly receives vibration from engine and road which then transfers to the internal mounting locations. It is important to understand dynamic characteristics and the components sensitive to vibration. The purpose of vibration analysis is to determine the strength of mountings. Practically natural frequency of each part should never match with engine excitation frequency over this range. But at some points we cannot avoid it, which will lead into resonance condition. For this we need to find not only natural frequencies but also the vibration amplitude at that point. This can be achieved by two methods i.e. by experimental analysis viz. by Electro dynamic shaker table and FEM analysis. First, carried out an experimental modal analysis to find the natural frequency and vibration modes. Then analyzed with FEM package, so as to compare working frequency with natural frequency for validation purpose.
