【摘要】：目的探讨某型坦克火炮静止射击和行进射击时舱室噪声与有害气体对乘员生理负荷的影响。方法测定坦克火炮静止射击和行进射击时舱室噪声、无机有害气体、总悬浮颗粒物(TSP)及挥发性有机物(VOCs),同步动态监测乘员心率、血压、血氧饱和度、听力及左右手握力等生理参数的变化情况。结果坦克行进时的连续噪声为107～112 dB(A),主要为低频,能量主要集中在300 Hz左右。射击时的脉冲噪声为167～172 dB(P),B-持续时间多为300-400 ms,作业后3 h乘员有轻度听力域移。坦克火炮静止射击和行进射击时舱室内主要有害气体以一氧化碳、二氧化硫、硫化氢、氨、TSP和总烃为主,其浓度随发射炮弹数目的增加而升高。伴随坦克静止和行进火炮发射,乘员心率、舒张压及血氧饱和度等生理参数发生了一定的变化。结论坦克火炮静止射击和行进射击时舱室噪声与有害气体对乘员的作业能力与身体健康可能产生了一定的影响。
[Abstract]:Objective to investigate the effects of cabin noise and harmful gas on the physiological load of crew during the firing of a certain type of tank gun at rest and marching. Methods the indoor noise and inorganic harmful gas were measured when the tank gun was still firing and marching firing. Total suspended particulate matter (TSP) and volatile organic compounds (VOCs) were monitored simultaneously and dynamically by the crew members' heart rate, blood pressure and oxygen saturation. Results the continuous noise of the tank was 107 ~ 112dB ~ (-1) A, which was mainly low frequency. The energy is mainly concentrated at about 300 Hz, and the pulse noise during firing is 167 ~ 172dB ~ (-) P ~ (-) -duration of 300-400 Ms. The main harmful gases in the cabin were carbon monoxide, sulfur dioxide, hydrogen sulfide, ammonia tsp and total hydrocarbon. Its concentration increases with the number of projectiles fired. The crew's heart rate is accompanied by the firing of tanks at rest and moving artillery. The physiological parameters such as diastolic pressure and blood oxygen saturation have changed to a certain extent. Conclusion the cabin noise and harmful gas may have a certain effect on the crew's working ability and health during the firing of tank gun at rest and marching firing. Ring.
