摘　　要：以火电厂再热器热端蒸汽管道为例,介绍了精确动态分析的步骤和方法,并运用水力分析软件Pipenet计算水(汽)锤力结果进行对比,结果表明后者更符合实际。计算管系响应时采用了时程分析的方法,并与响应谱分析方法结果进行比较,得出了精确的动态响应结果。Taking the steam pipeline at hot end of reheat system in fossil-fired power plant as an example,the procedure and method of a precise dynamic analysis method has been introduced.The water（steam） hammer calculated manually has been compared with that by hydraulic calculation software PIPENET,and the latter is found to agree well with actual conditions.The time history analysis method is adopted in the calculation,which is compared with the result of response spectrum analysis so as to obtain a precise result of dynamic response.
