Cost and Performance Benefits for Laminated Steel Body 1999-01-1784

This paper will suggest, through the results of the APAMAT Insertion Loss test, the cost and performance benefits of constructing a body component part from laminated damped steel. For the purposes of demonstrating this point, the sample used in the test setup was viewed to be the body component part of interest. The variations of acoustical materials tested were then comparable on a benefit per cost/weight basis. Under the definition for the APAMAT Insertion Loss test, the sample used in this study simulates the excitation a sheet metal part undergoes in the vehicle body and measures the efficiency of the materials to reduce noise. By Integrating vibration damping into the part structure with laminated damped steel, these results will demonstrate potentials in overall vehicle savings in a “take away” of weight, material and manufacturing costs.
