多次冲击试验机的冲锤的“自身疲劳”是设计制造的关键。本文针对要求试验的寿命长,冲击能量要求低,但能量低就得要求冲锤本身质量轻。为此设计与制造了轻型冲锤,从理论上、结构上、材料上选择最佳因素,从而提高冲锤寿命。图7幅,参考文献4种。 Repeated impact testing machine hammer “self-fatigue” is the key to the design and manufacture. In this paper, long life expectancy required for the test, low impact energy requirements, but the low energy requirements of the hammer itself light weight. To this end, the design and manufacture of light hammer, in theory, the structure, the material to choose the best factor, thereby improving the life of the hammer. Figure 7, 4 references.
