Structural dynamics analysis report Apollo 14 LRRR

Abstract

The attached structural analysis is divided into three sections. Section I presents the component level stress analysis. This analysis is based on an assumed limit loading of 20g's in any direction. Section II is the dynamics analysis of the structure designed on the basis of the 20g limit load assumption. Section II shows that in general, limit loads are below those assumed in Section I, but that exceptional forces do occur in some locations. Section III is a computer analysis of the redundant grid structure based on the load patterns derived in Section II.
