Impact and Vibration analysis of Audi Car Bumper with Different Composite Materials

A bumper is a structure attached to or integrated with the front and rear ends of a motor vehicle, to absorb impact in a minor collision, ideally minimizing repair costs. Stiff metal bumpers appeared on automobiles as early as 1904 that had a mainly ornamental function. Numerous developments, improvements in materials and technologies, as well as greater focus on functionality for protecting vehicle components and improving safety have changed bumpers over the years. Bumpers ideally minimize height mismatches between vehicles and protect pedestrians from injury. Regulatory measures have been enacted to reduce vehicle repair costs and, more recently, impact on pedestrians Static Structural and Modal Analysis of Car Bumper has been conducted for different materials for bumper surface Epoxy carbon UD and carbon fibre composite and for supporting structure Structural steel and Aluminium B390 alloy. With the aid of CAD analysis model is analyzed for the same load and boundary conditions. CAD analysis is the best solution of the available to provide the efficient results for the model analysis, model the created and boundary conditions and loads are applied as per the requirement. Model is meshed and elements are created as per the material grain structure by analysis tools and proper meshing of the component provides the exact solutions for the model. Same procedure is used for the car bumper analysis with different materials and decision is done based on the model test analysis for the best suited.
