计算时间减少了95%

计算精度满足工程要求

为密闭爆炸容器的强度设计提供了一种快捷的仿真方法.

Abstract

In order to seek a fast and accurate method for simulating the dynamic response of closed vessel under explosion load

"LOADBLAST"

an explosion load model provided by LS-DYNA was used to simulate the load process of detonator blasting in spherical closeness container.For some characteristic points of a specific vessel

several equivalent stress time-history curves and the stress variation nephogram at different times were obtained.The deviation was small between the obtained results and those from engineering algorithm.Compared with the fluid-solid coupling method

the proposed load model reduced the number of grid by 80% and the computing time by 95%

and the computation precision can satisfy the project's request.The method provided a shortcut simulation method for the intensity design of closeness explosion vessel.
