伴随计算机仿真技术的应用,管道冲击压力分析的方法和手段越来越丰富,使得在冲击压力计算方面更加方便和直观。对飞机燃油系统有压管道冲击压力(在民用水利系统称为水击)产生的原因及造成的危害进行了初步分析,介绍了几种冲击压力的分析计算方法,并指出某型飞机燃油系统管道可能出现的冲击压力及产生的故障,提出了防止冲击压力发生的措施。
With the application of computer simulation technology, the method and means of pipeline impact pressure analysis are more and more abundant, making the calculation of impact pressure more convenient and intuitive. The causes of the pressure buildup on the aircraft fuel system (the water hammer in the civil water system) and the harm caused by it are analyzed preliminarily. Several analytical methods for calculating the impact pressure are introduced. The paper also points out that some aircraft fuel system pipes Possible impact pressure and the resulting failure, put forward measures to prevent the occurrence of impact pressure.
