Description

Technical Field

[0001] The present invention specifically relates to an experimental device for simultaneously measuring the comfort and stability of a single - soldier helmet, and pertains to the field related to experimental equipment for helmet comfort and stability. Background Technique

[0002] Currently, research on helmet comfort has shown that the main cause of headache is the pressure exerted by the heavy helmet worn during missions on the occipital nerve. The size of the buffer zone between the top of the head and the helmet when wearing the helmet plays a crucial role in the protection of soldiers. At the same time, researchers have begun to pay attention to the thermal effect on soldiers. Previous studies have not conducted further analysis: the coupling relationship between pressure and pain, the relationship between the thickness of the buffer area and the thickness of the comfortable padding, and the relationship between the internal heat dissipation effect of the helmet and comfort have not been clarified.

[0003] Helmet comfort has always been the focus of the evaluation of single - soldier equipment accessories, but it has not been well solved for decades. In particular, domestic scholars still pay less attention to this aspect. The experimental device can simultaneously test the heat transfer and air permeability, pressure distribution, and stability of a single - soldier helmet. And through Bluetooth, it can quickly process data and store the results, greatly reducing the labor cost of the experiment. Summary of the Invention
