Effect of the composite material of the car's bumper on its fundamental natural frequency and response as a result of car vibration

الملخص EN

-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
