Abstract In order to get charging amount for precisely separating a titanium alloy sheet, the dimensional analysis method was applied to determine main influence factors of a test, and abstract the geometric similarity law. Numerical simulation was used to predict the charging amount for precisely separating a titanium alloy sheet by means of the SPH method in the explicit finite element analysis program AUTODYN. Through adjusting structures of decoupled charge and spaced charge and accurately controlling charge parameters, finally the charging amount was determined with tests to obtain the optimal proportional relation among minimum wall thickness, charging diameter and cushion layer. The test results were compared with numerical simulation ones. It was shown that both results are very close to each other; the feasibility of the study ideas is verified; the proposed method provides a reference scheme for determining charging amount of explosive separation components in complicated engineering environment.
