摘要

研究了孔径、孔间距和孔排列对闭孔泡沫铝吸能能力的影响。采用实验设计和有限元法确定了吸能孔的最佳排列方式。简单立方结构的铝6063吸能效率最高，而简单立方结构的铝356吸能效率最低。随着载荷速率的增大，参数t对两种结构的影响均大于h。响应面法提出的模型被认为是有效的，实验值与预测值之间的差异在15%-20%之间。

Closed-cell aluminum foams with spherically-adjustable pores: Numerical and experimental investigation of effective parameters

The study investigates the effects of pore diameter, pore spacing, and arrangement on the energy absorption ability of closed-cell aluminum foam. The optimal arrangement of pores for energy absorption was determined using experimental design and the finite element method. Aluminum 6063 with a simple cubic structure was found to be the most efficient at energy absorption, while aluminum 356 with a simple cubic structure was the least effective. As the load rate increased, the effect of the parameter t exceeded that of h in both structures. The response surface method’s proposed model was deemed effective, with the difference between experimental and predicted values around 15%–20%.

期刊介绍： Manufacturing industries throughout the world are changing very rapidly. New concepts and methods are being developed and exploited to enable efficient and effective manufacturing. Existing manufacturing processes are being improved to meet the requirements of lean and agile manufacturing. The aim of the Journal of Engineering Manufacture is to provide a focus for these developments in engineering manufacture by publishing original papers and review papers covering technological and scientific research, developments and management implementation in manufacturing. This journal is also peer reviewed. Contributions are welcomed in the broad areas of manufacturing processes, manufacturing technology and factory automation, digital manufacturing, design and manufacturing systems including management relevant to engineering manufacture. Of particular interest at the present time would be papers concerned with digital manufacturing, metrology enabled manufacturing, smart factory, additive manufacturing and composites as well as specialist manufacturing fields like nanotechnology, sustainable & clean manufacturing and bio-manufacturing. Articles may be Research Papers, Reviews, Technical Notes, or Short Communications.
