摘要

Previous studies demonstrated that the currently used ballistic inspection of M-1 helmets could be replaced by an inspection based on thickness requirements. The objective of the current study was to identify the most effective way to perform the inspection in production situations, and to make a preliminary design of a thickness inspection system. Several thickness-measuring methods were evaluated. Consideration was given to ultrasonics, electromechanical and pneumomechanical devices, radiological methods, and eddy current methods. Approaches based on both averaging and minimum seeking systems were considered. (Author)
