| Abstract: | By using the finite element method, the dynamic stress caused by vertical contact impact between bolt locking surface and barrel extension locking surface of a new rifle was studied. The finite element models were developed in three different cases, and the numerical simulation was processed. The distribution and variation regulations of the contact stress on the locking surface were analyzed. The value and the location of the maximal contact stress on the contact surface in three cases were compared. The calculation results show that the strength of the locking mechanism is proper. |
