摘　　要：强碰撞中型冲击机是GJB150.18-1986规定的标准考核设施之一,它主要对于质量介于120 kg～2.7 t的舰船设备进行冲击考核,用于评定舰船设备的抗冲击能力[1]。美国的中型冲击机经过大量的冲击环境试验,经过总结制定MIL-S-901系列中的标准考核工况,我国的中型冲击机仿照美国来设计,考核标准也参照美国标准来制定,但我国中型冲击机的冲击环境特征是什么,影响冲击环境的因素是什么,现有标准存在的问题是什么还不是十分清楚。针对这些问题给出我国中型冲击机应满足的冲击环境要求,提出我国舰船设备抗冲击考核标准的改进建议。High-Impact medium-weighted shock machine is one of the standard check-up facilities prescribed in GJB 150.18-1986. It is used to mainly assess the anti-shock ability of the ship＇s equipment whose mass is from 120 kg to 2 700 kg. Based on a large number of shock environment tests for medium-weighted shock machines, the standard check-up conditions for MIL-S-901 machines were worked out in the United States. Our medium-weighted shock machines were designed after American design standard, and the check-up standard was also specified following American standard. But we have not yet known clearly the feature of the shock environment of shock machines, the influencing factors of shock environment and the problems in the current standard in our country. Therefore, aiming at the requirements in the shock environment of shock machines, some suggestions for improvement of the standard for anti-shock check-up of ship＇ s equipments were proposed.
