Abstract

In the anechoic chamber, the wave-absorbing material consists of carbon impregnated foam cones. The conventional installation consists of bonding the bases of the cones directly to the steel wall of the chamber with adhesive.

Structural Support System for Anechoic Liner

In the anechoic chamber, the wave-absorbing material consists of carbon impregnated foam cones. The conventional installation consists of bonding the bases of the cones directly to the steel wall of the chamber with adhesive.

Because of irregularities in the wall, inconsistent installation, and the weight of the stacked cones, deformation occurs, and the life of the system is unsatisfactory. Cones are stacked five high, resulting in a force of approximately 360 pounds on the bottom cone. This compression caused deflection in the cone stacks, resulting in tnsion being placed on the adhesive bond which then fails.

The system devised provides a mechanical/structural support for each layer of cones such that no layer is supported by any other layer. Each cone 1 is notched and built into a shelf system. Each shelf 2 is constructed such that the cones are supported past their center of gravity so that no deflection can occur, yet the shelves are not visible.

The shelves 2 and support posts 3 are constructed of wood which will not interfere with the wave-absorbing quality of the system. Tests have shown no reduction in quality. Rear shelf supports are welded directly to the wall, giving further stability to the system.

The advantages of this system are:

1. System life is greatly increased; no deflection can occur.

2. System can be disassembled and altered with no damage to

the cone material, providing versatility in expanding...
