退壳机构
退壳机构-
对自动机、供弹机构、击发机构和退壳机构进行了运动学和动力学分析，进行了各机构运动可靠性的验证，确定了关重件在工作过程中所受的载荷谱。
Kinematic reliability and load spectrum which suffered in the course of their work are proved by kinematics and dynamics analysis of automatic mechanism , trigger mechanism , the feed mechanism and the extraction and ejection mechanism .
