On the Use of Filament Wound Toroids as Pneumatic Shock Absorbers.

Abstract

This report contains the results of a study on the use of filament wound toroids as pneumatic shock absorbers. Expressions for the specific energy absorption under isobaric and adiabatic conditions are derived and compared with the performance of competing systems. Means for improving stroke efficiency are discussed. The stiffness properties of a compressed toroid under combined compression, bending and shear are derived analytically and compared with experimental measurements. In addition the buckling behaviour of a compressed stack of toroids is analyzed and compared with test results. In both cases the agreement between analysis and experiment is sufficiently good to validate the theory for engineering calculations.
