FORCED VIBRATIONS OF A VISCO-ELASTIC CYLINDER CASE-BONDED TO A THIN ELASTIC SHELL

摘要

This paper is concerned with the forced vibrations of case-bonded solid propellant grains. Special attention is paid to the interaction between the thin elastic shell (case) and the thick-"walled propellant cylinder. The effects of material damping in, the propellant are explored.nFrequency-response functions are computed, which can be used for analysis in situations where the loading is arbitrary deterministic or ran don (stationary).
