摘要: 分析了TNO(The Netherlands Organization)多能法在工程应用中存在的问题,并提出相应的解决方法,以提高其工程应用可操作性.归纳并提出了选取爆源强度等级的依据;为解决多能法在应用过程中手工查爆炸波特征曲线图读数易带来误差的问题,采用TNO爆炸波特征曲线拟舍关系式代替TNO爆炸波特征曲线,并对该关系式中部分误差较大的计算式进行修正;根据爆炸波对人体肺、耳的伤害需达到的超压值和多能法特征曲线的拟合关系式,利用迭代法和最小二乘法拟合出爆炸波导致不同程度人员伤害距离的关系式,并对其进行验证.该关系式形式简单,输入参数少,可用于工程实践.

Abstract:

This paper focuses on the engineering applications of TNO(The Netherlands Organization)Multi-Energy method,analyzes the existing problems and provides corresponding solutions to improve the applicability of the method,in addition to the rules to select the strength grade of explosion source.In order to avoid the error due to the manual reading from blast wave curves,the characteristic curves of TNO blast wave are replaced by their fitting expressions,and some of the expressions resulting in big eror are modified.Moreover,according to the overpres-sure causing injury to the lung and the eardrum,as well as the fitting expressions of the characteristic curves,the expressions describing diferent injury distances are deduced by ineans of the iteration method and the least square method and are further verified.It is shown that the proposed expressions are feasible in engineering because their formats are simple and few inputs are needed.

Key words: TNO Muhi-Energy method, engineering application, vapour cloud explosion (VCE), explosion source strength, injury distance
