摘　　要：中量级强冲击试验机是《军用设备环境试验方法冲击试验》(GJB 150.18—1986)规定的标准考核设施之一。其冲击环境特性的研究对冲击机试验具有十分重要的作用。我国的中型冲击机仿照美国进行设计,考核标准也参照美国标准制定,导致我国对中型冲击机的冲击环境特征、影响冲击环境的因素、现有标准本身及应用中存在的问题不是十分清楚。为了探索中型冲击机冲击环境特性,对中型冲击机进行了多次试验,对冲击响应结果进行分类与对比研究,得出了冲击环境特性,并通过结果进行拟合,预测不同工况下的冲击环境。The medium-sized strong impact testing machine is one of the standard assessment facilities specified in the Environmental Test Methods for Military Equipments Shock Test(GJB 150.18-1986).It is very important to study the characteristics of impact environment for the experiment of impact machine.China’s medium-sized impact ma⁃chines were designed in imitation of the United States,and the assessment standards were also formulated with refer⁃ence to American standards.As a result,it wasn't clearly for Chinese to the impact environment characteristics of medium-sized impact machine,the factors affecting the impact environment,the existing standards themselves and the problems existing in the application.In order to explore the impact environment characteristics of the medium sized impact machine,the medium-sized impact machine had been tested for many times,and the impact response results obtained were classified and compared,and the impact environment characteristics obtained were matched by the results to predict the difference Impact environment under working conditions.
