摘　　要：介绍了一种在模拟井下作业环境全封闭形式的空间里,检验铝合金材料在一定重量的重锤作用下,从特定的高度自由落体冲击摩擦锈蚀钢板是否产生火花并引燃气体的试验装置。论述了整套自由落锤火花试验装置的工作原理、关键部位的设计思路、整套试验的工序流程。It is introduced a test set which can verify the spark caused by a heavy bob with a given weight from a specified height to the tested meta steel plate covered by a metal with a given content of the aluminum alloy under the simulated space- full enclosed underground work atmosphere. It describes the operating principle, designing of the key parts, the whole process flow for the spark test device with free falling hammer.

关 键 词：铝合金 自由落体 摩擦 火花
