摘要 根据泡沫材料的动态特性,采用最佳吸能效率图取代吸能图的方法,进行泡沫金属缓冲器设计。比较表明这种方法是合理的,具有更好的通用性与操作性。以泡沫铝为例,具体阐述了最佳吸能图在泡沫铝缓冲器优化设计中的应用。 The dynamic properties of foam materials are analyzed, and an optimum-energy-absorption efficiency diagram is used in foam metalic buffer design to substitute the conventional energy-absorption diagram. By comparison and analysis, it shows that the new diagram is feasible and more universal, and operated more easily than the conventional. As an example, an application of the optimum-energy-absorption diagram is described in the optimization design of foam aluminum buffer.
