Head force applying and measuring device

Abstract

The invention discloses a novel head force applying and measuring device which comprises a fixing base frame, a liftable unit, a head partitioning device, a force applying unit and a force measuring unit. The fixing base frame and the liftable unit achieve general applicability, the head partitioning device achieves head partitioning, force is applied to different regions of the head through an electronic pressurizing pump controlled by an electronic control system in the force applying unit, the applied force is measured through a pressure intensity sensor in the force measuring unit and converted into electric signals to be transmitted into a computer unit to be displayed and recorded, and the result of the force measuring unit can control the force applying unit to apply precise and uniform pressure to the head specific region. The device can be applied to researching the relation among ergonomics cognitive power, comfort level and different region stress magnitudes of the head of apilot, the best force application mode is searched for to help to optimize the mechanical property of the pilot helmet design so that the high comfort level can be achieved, and the device conforms to ergonomics cognition of the pilot.

Description

technical field [0001] 1. The present invention relates to a device for applying force and measuring force, in particular to a device for applying force to the head and measuring force. Background technique [0002] 2 The helmets worn by pilots are mostly made of light materials such as fiberglass or plastic, which are mainly used to prevent head shocks or bruises, and can prevent noise. This kind of helmet can cover the ears and cheeks, and is equipped with earphones and microphones, etc., and some are also equipped with masks that can move up and down to protect the eyes and face. Despite the use of lightweight materials, the weight of the helmet is still about 2 kilograms. The pressure on the pilot's head will affect the pilot's ergonomics cognition, and will cause problems such as the reduction of the pilot's operating efficiency. [0003] 3 The comfort of the pilot's helmet has an important impact on flight safety and operational effectiveness. The current research on...

Problems solved by technology

[0004] 4 However, the aforementioned experiments only deduce the comfort level of the helmet through simulation technology and model experiments, and the research on evaluating the comfort level of the helmet head pressure from the perspective of ergonomics cognition is still blank

Therefore, research on the relationship between the magnitude of pressure on different areas of the head, their relationship and ergonomic cognition is urgently needed
