摘　　要：为了研究梭式爆破保护装置关闭时的流场特性和分析爆破保护装置关闭时的动态特性,采用数值仿真计算方法。以ADINA软件为平台,对DN50梭式爆破保护装置进行仿真计算,验证了流体阻尼器在梭式爆破保护装置关闭过程中起到了很好的缓闭作用,使阀芯在闭合过程中快速平稳,减小了水击,有利于它进一步的研究与应用。In order to research the characteristics of flow field about the shuttle-type rupturing protection device in the closed process,and to analyze the dynamic characteristics of shuttle-type rupturing protection device in the closed process,numerical simulation method was used.In AIDNA software,simulation calculation to the DN50 shuttle-type rupturing protection device was completed.It is verified the fluid damper plays the role of shutting down slowly in the closed process of the shuttle-type rupturing protection device.In the same time,the valve core closes rapidly and smoothly.Meanwhile,water attack is reduced.Based on the above advantages,it is helpful for the further research and extension.
