Natural frequencies and mode shapes of a semi-cantilevered mount, used to interface a night vision scope to a 0.50 caliber machine gun, are studied to determine the overall night vision scope mounting bracket assembly dynamic behavior. With this information and information from further modal testing of other redesigned brackets, the engineer can determine whether a proposed design modification will produce the desired change in the dynamic behavior of the night vision scope mounting bracket. The practical importance of obtaining this information lies in the fact that redesigned brackets can be modal tested to determine which bracket is the best for live fire field testing. The time and money saved by using the computer-generated modal model for analyzing the redesign is significant.
