Abstract:
The advantages of buckling isolators over presently used military standard isolators for the protection of equipment aboard high performance jet aircraft are discussed. The dynamic performance of various foams is compared to the theoretical behavior of buckling isolators based on the experimental results obtained with polyurethane foams. Design guides are presented for the use of polyurethane foams in multifunctional vibration and shock isolation systems based on the experimentally determined dynamic properties of the foam material. Results of tests performed on 1 ATR B1-D1 size electronic equipment bases, designed and manufactured in accordance with design curves generated for a particular polyester foam, are presented and indicate the suitability of optimizing the use of a particular foam in an isolation system which is to meet specific performance requirements. General manufacturing and quality control techniques applicable to foam isolation systems are discussed. Recommendations for further work are made regarding the generation of design curves for other foams and the effect of combined environments on applicability of the design guides. Author
