Allowance test assessment method for mild detonation fuse separation device

The invention belongs to the technical field of spacecraft structures, and relates to an allowance test assessment method for a detonation fuse separation device, and specifically relates to a test method for comprehensively assessing separating property allowance and structure dynamic strength margin of a mild detonation fuse separation device. The method uses a mild detonation fuse which contains 120% design explosive quantity to perform the structure dynamic strength margin test, so as to assess the anti-explosion impact property of residual structures of a protective cover and a separation ring under high explosive quantity, and ensure integrity of the structures. A test sample whose centering deviation is relatively large is used, and a mild detonation fuse in 67% design explosive quantity is used to perform a separating property allowance test, so as to assess low explosive quantity separation reliability in centering deviation. The method can fully verify the separating property allowance and structure
