Development of Mechanical Impedance Techniques to Analyze Weapon Mount Interfaces.
Abstract
A technique for determining the impedance of weapon mounts is being developed by personnel of the Research Directorate, Weapons Laboratory at Rock Island. This technique involves the use of the firing pulse of the weapon. Results of the study have indicated that the firing pulse may induce frequencies of which the maximum one could be ten times greater than the dominant resonant frequency of the system. Programs to acquire and reduce data from firing tests in real and delayed time have been prepared. The Fourier transformation of force and velocity, measured at the weapon mount interface and obtained in previous programs, will allow calculation of mount impedance. The theory required to analyze the weapon mounts and the results of real-time and delayed-time analysis programs for weapon test data are presented in this interim report. (Author)
