The aerospace structures and equipment experience severe shock loading during the inter-stage separation,which is conducted by the high energy explosion of the pyroshock devices.Therefore,it is important to determine the shock response of the cabin structure,which is typically a cylindrical shell,under separation shock loading.The separation experiment of a cylindrical shell is performed,and the shell is cut into two parts along the circumferential direction by the flexible linear shaped charges.The influences of the charge amount and the distance from the explosive source on the response of the structure are investigated.The transient problem of the cylindrical shell under shock loading is also modeled and simulated numerically,using LS-DYNA.This research is helpful for the prediction of the shock response and the damage estimation of the shell structures under pyroshock loading.
