Dynamic Response of the M113 Gun Tube to Travelling Ballistic Pressure and Data Smoothing as Applied to XM150 Acceleration Data
1975
Abstract : This work is concerned with the response of the M113, 175mm gun tube to the travelling interior ballistic pressure pulse initiated upon firing. The analysis was performed by the NASTRAN finite-element computer code. Initial results indicate that peak dynamic stresses (axisymmetric) can be significantly greater than the static Lame stresses - normally computed for design purposes. The results compare favorably with strain data accumulated during test firing programs conducted by the Ballistic Research Laboratories at Aberdeen, Maryland.
