Sizing Strategy for the Advanced Modular Multi-threat Protective Headwear System

摘要

The Advanced Modular Multi-threat Protective Headwear System Technical Demonstration Project (AMMPHS TDP) aims to 'provide improved blast, ballistic, and impact protection as well as modular and scalable coverage for mounted and dismounted operations'. New concepts are being proposed to achieve this and the challenges are numerous from materials to design aspects. One of the challenges facing this project is to ensure that the helmet system will fit its intended population and provide the degree of coverage and protection required. A new tool was created that condensed a large amount of three- dimensional (3D) laser scan data and made it easily accessible. This new tool provides a glimpse into the internal structure of the data and provides unparalleled knowledge of the main modes of variation of Canadian Forces (CF) head shapes. From this, a set of design head forms was derived that captures about 50% of this variability and allows designers to build in the necessary adjustments. While the proposed strategy captures roughly 50% of the variability, the next step would be to examine a few more of the principal components, assess their relevance to the design of the AMMPHS, and compare the head forms generated in this way with the ones proposed herein. The goal would be to determine whether or not they provide additional information.
