Testing and evaluation system for wear comfortableness of helmet

Abstract

The invention relates to a testing and evaluation system for wear comfortableness of a helmet. The testing and evaluation system for the wear comfortableness of the helmet comprises a head modular matrix, a sensing device and a data analysis system, wherein the data analysis system is arranged in a computer; the sensing device comprises an undersurface silica gel layer which can be fitted with the curve shape of a head; the upper surface of the undersurface silica gel layer is provided with a matrix network which consists of a plurality of pressure sensors and a lead vertically and horizontally connected with all the pressure sensors; the exterior of the matrix network is connected with a power module and an acquisition control module through leads; the data analysis system comprises a data management unit, a data storage unit and a work efficiency performance analysis unit; the data management unit comprises an open module and a sampling module; and the work efficiency performance analysis unit comprises a pressure mode module, a pressure peak module, a pressure mean value module, a pressure center module, a pressure variance module and a pressure standard deviation module. The testing and evaluation system for the wear comfortableness of the helmet can be widely used for evaluating the wear comfortableness of products, such as various military helmets, helmets for polices, civil helmets, safety helmets, sports helmets and the like.

Description

technical field [0001] The invention relates to a test and evaluation system, in particular to a helmet fit test and evaluation system. Background technique [0002] Modern helmets are used to prevent projectiles or fragments from penetrating the head, prevent the head from directly colliding with hard and high-energy objects, effectively protect the human head, eyes, and face, and do not affect the human body's vision and activities. It is used in military , medical, sports, entertainment and other industries have a wide range of applications. In order to ensure the rationality of the ergonomics of the entire helmet, countries around the world have carried out in-depth research on 3D head shape acquisition, modeling and standardization. Jeffrey M.T. of the U.S. Air Force Operations Center used the KGR30 mass analyzer produced by Cosmos Electronics to test and study the center of gravity of the "head model-flying helmet" system, but the research did not directly measure the...

Problems solved by technology

Asko V. of the University of Melbourne in Australia established a set of evaluation devices for the dynamic performance of the SPH-4 helmet, but the device is relatively complicated and is greatly affected by the physiological factors of the helmet wearer.

At present, most of the helmets on the market in my country are designed according to the face and head shape of Westerners. The reason is that the production process of the helmet lacks the corresponding head molds that conform to the Chinese head shape.

In addition, there are few objective evaluation methods for helmet shape, helmet comfort, and stability at home and abroad, and there is almost no overall quantitative test and evaluation of fit.
