计算表明,滑动摩擦系数选取对钻地弹侵彻深度有较大影响,进而分析了弹体改变对滑动摩擦系数的影响。
Through the calculation, the choice of coefficient has rather great influence on the depth of projectile penetration. Then the influence of the change of projectiles on the coefficient is analyzed.
通过建立砂粒自锁条件及实测长石砂岩、石英砂岩与泵筒镀铬层或氮化层的滑动摩擦系数值,证实了对柱塞拉伤失效原因的推测是正确的。
The deduction is confirmed by establishing self locking conditions and determining the sliding friction coefficients between sand and chromium plating layer and between sand and nitrided surface.
