摘　　要：采用数模试验的方法对火力发电厂主要蒸汽管道汽锤的影响因素和影响程度进行分析,得出汽锤力与阀门动作时间、管道规格、机组容量、机组参数等影响因素的关系,并分析了汽锤对不同蒸汽管道的影响及动态荷载的工况组合,提出了控制动态荷载危害的措施。Numerical simulation test has been applied to analyze the influence factors and degree of steam hammer load on the main steam pipe in coal-fired power plant. The relationship between steam hammer forces with various influence factors has been obtained. The influence of steam hammer on different main steam pipes and the dynamic load combination have been analyzed. Measures on controlling dynamic load hazards have been put forwards.
