Evaluation of two cooling systems under a firefighter coverall

Firemen often suffer from heat strain. This study investigated two chest cooling systems for use under a firefighting suit. In nine male subjects, a vest with water soaked cooling pads and a vest with water perfused tubes were compared to a control condition. Subjects performed 30 min walking and 10 min recovery in hot conditions, while physiological and perceptual parameters were measured. No differences were observed in heart rate and rectal temperature, but scapular skin temperature and fluid loss were lower using the perfused vest. Thermal sensation was cooler for the perfused vest than for the other conditions, while the cool pad vest felt initially cooler than control. However, comfort and RPE scores were similar. We conclude that the cooling effect of both tested systems, mainly providing a (temporally) cooler thermal sensation, was limited and did not meet the expectations.

Mechanical properties of high-strength concrete after fire

With compressive strength grade of C40, C60, and C70, respectively, normal-strength concrete (NSC) and high-strength concrete (HSC) were used to investigate compressive strength, splitting tensile strength, and bending strength after high temperature. The oil furnace is used in this study. Its temperature-time curve is close to standard curve, which conforms to Chinese standard GB/T 9978-1999. After being heated to temperatures of 200, 400, 600, 800, and 1000 °C, respectively, the mechanical properties of HSC were tested. The influence of temperature, water content, specimen size, strength grade, and temperature profiles on mechanical properties of HSC are discussed.

运载火箭六自由度仿真平台搭建与应用

研究运载火箭六自由度仿真系统设计问题,在传统火箭六自由度仿真平台设计中常以特定任务为导向,造成仿真系统碎片化严重,扩展重用性不足.同时,数值仿真与视景仿真的交互中存在实时驱动的问题.针对上述问题,采用面向对象的模块化设计方法,建立了运载火箭六自由度仿真模型,给出了三层结构的通用仿真框架.设计了仿真消息管理器,较好地解决了数值仿真与视景仿真的集成并保证了系统的实时性.仿真结果验证了模型建立的准确性以及仿真平台的可靠性和稳定性.仿真结果对于运载火箭设计和性能评估系统的建立有着良好的借鉴意义.     

Interactions of Impact Shock Waves in a Thin-Walled Explosive Container. II. Impact by a Cone-Nosed Projectile

Interaction of impact shock waves that could detonate an explosive (Composition B) confined in a thin-walled container impacted by a cone-nosed projectile is numerically studied, based on the Forest Fire explosive reaction rate model. The normal impact on the container by a small projectile with a conical nose is considered. Depending on the cone angle of the nose part of the projectile, the zone of interaction of initiating shock waves can be remote from the central axis of the impact. The off-the-central-axis detonation is interpreted from the viewpoint of different interaction modes in the explosive container, which are reflected from the cassette wall, change their directions, and superimpose onto each other, leading to explosive detonation.
