Abstract
Effect of vibration on the car's bumper was studied in this paper.
Composite materials are used in manufacturing the car's bumper. The methods that
used in this investigation are Rayleigh's formula for lumped masses in addition to
super position method and the mixture rule. By using these techniques it can be
found the natural frequencies, mode shapes and deflection for the car's bumper.
Different matrix material (resin), fibers and volume fraction are used in this
investigation. MATLAB program are built in this study. The results of this
program are compared with the results of the ANSYS 11 program. The
comparisons show good agreement.
