基于暖体假人实验的防刺服热阻和湿阻研究

为有效提高防护服装舒适性、降低人员体力消耗、加快人体防护装备研制与开发,开展了利用出汗暖体假人测量防刺服在不同环境下的热阻与湿阻特性的研究.根据国际标准,假人只适用于常温环境下服装的热阻和湿阻测量.对原有热阻模型进行修正,结合热电偶测量方法以及暖体假人测量技术,实现高温下防刺服热阻和湿阻测量.在温、湿度可控制的气候室内,设置不同环境工况,获得两套防刺服的热阻和湿阻特性,比较了不同防刺基板材料对防刺服热阻和湿阻的影响,以及防刺服不同部位热阻和湿阻的差异.实验结果表明,防刺服热阻随着温度升高而降低;而湿阻随着环境温度升高而增大,随着湿度增加而减少. 

Investigation on Thermal Insulation and Vapor Resistances of Stab-Resistance Body Armor Using Thermal Manikin Method

To improve the wearing comfort of body armor and decreasing human energy consumption, a thermal manikin was used to investigate the thermal insulations and vapor resistances of two stab-resistance body armors in a temperature and humidity individually controlled climate chamber. Thermal manikin was generally applied to evaluate the thermal insulation and vapor resistance in room temperatures based on the international standards. In this paper, the general thermal insulation model was revised by combining the thermocouple detection method and thermal manikin measurement method. The effects of air temperature and relative humidity of the climate chamber, and stab-resistance material on the thermal insulation and vapor resistance were studied. The results show that the thermal insulation increases with the air temperature decreasing; the vapor resistance increases with the air temperature increasing, and decreases with the chamber relative humidity increasing.
