基于心率和喷水效率的森林灭火手泵性能评价

森林灭火手泵的人机操作界面的优化设计极为重要，该文针对普遍应用的国内外3款典型手泵产品，从心率、喷水效率、主观评价等方面进行了性能评价。方差分析表明:手泵类型、握持姿势、喷水频率对心率的影响很显著，美国产手泵（S1）作业时的心率增加比率最大，加拿大产手泵（S3）最小。在背负手泵水箱（袋）步行时，S1水箱携带时的心率增加比率最大，中国产手泵(S2)水袋携带时最小。S3的喷水速率最大，S1最小；S1的射程最大，S2最小。主观评价结果表明S3最优，S1最差。综合分析上述结论认为，针对现有3款手泵，S3的水枪和S2的水袋相组合是最佳的组合模式。 

Assessment on the performance of hand pumps for forest fire suppression based on operator's heart rate and water spraying efficiency

Hand pump is one of the most widely used portable machines for controlling forest fires.During the process,operators bear heavy physiological load because of the load of water bag and water spraying pressure,which is caused by water gun frequently.Therefore,it is important to optimize the design for geometrical parameters of human-machine interface of hand pump.Based on heart rate,subjective assessment,water-spraying rate and water-spraying distance,this paper assesses the performance of three types of repr...
