摘要
对１２５ｍｍ滑膛模拟弹发射过程中的应力应变场进行了数值计算，结合计算给出了ＡＤＩＮＡ程序计算材料非线性大位移的求解策略，并以炮管长度和弹丸出膛时间等为控制量，对各种求解途径进行了比较。
In this peper,a numercal calculation of strain and stress on projective process of 125 mm imitative bomb is preformed by using the ADINA program,a method of nonliear dynamic large displacement is proposed by compard different calcuating routes.
