An investigation was conducted by the Research Directorate, Weapons Laboratory at Rock Island to determine the structural dynamic characteristics of the M122 Tripod Mount with enough generality to be applicable to other tripod mounts of the same general configuration. The M122 Tripod Mount was mathematically modeled as a system of equations. This model is compatible with the mathematical model of the weapon developed by the USAWECOM to produce a combined weapon-mount mathematical model. Two models of the weapon-mount system were developed. The first was a linear description in which the mount was modeled as a spring with three degrees of freedom. The second was a nonlinear model where the forward leg of the tripod mount could lift off the ground as the mount is rotated about its aft two foot-pads. Author
