Study of Man-Weapon Reaction Forces Applicable to the Fabrication of a Standard Rifle Firing Fixture.
Abstract
A study was conducted of the man-weapon interaction force relationship to define the parameters to be incorporated in the design of a universal small arms test fixture, that simulates man as a flexible mount. This report contains the results of Phase I of the program, which is to provide the engineering data and preliminary drawings required for the fabrication of a prototype test fixture. To demonstrate the feasibility of designing a universal mount fixture, a three degree of freedom mathematical model was developed that simulates the man and weapon as a coupled dynamical system. A sensitivity analysis was performed on both analog and digital computers to determine which of the system parameters are critical to the design of the mount and to obtain bounds on them. The mathematical simulation was supported by an extensive test firing program, involving shooters of various sizes firing the M16 rifle and the M79 and M203 grenade launchers. In these tests the shoulder reaction force and the dynamical motions of the man-weapon system were recorded.
