Experimental studies on the axial crash behavior of aluminum foam-filled hat sections

WANG Qing-chun, FAN Zi-jie, GUI Liang-jin, WANG Zheng-hong, FU Zi-lai

Frontiers of Mechanical Engineering 2006, Volume 1, Issue 4, Pages 381-387 doi: 10.1007/s11465-006-0044-9

Abstract: Drop hammer tests were carried out to study the axial crash behavior of aluminum foam-filled hat sectionsFirst, the axial crash tests of the empty hat sections, aluminum foam and the aluminum foam-filled hatsections were carried out; then, based upon the test results, the axial crash behavior of the aluminum

Explicit optimization method for cutting-screw-thread on the basis of dual-RSM

Zhengbao LEI, Shubin WEI, Qingyun DU

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4, Pages 423-430 doi: 10.1007/s11465-010-0109-7

Abstract: To obtain the explicit function for optimizing the cutting-screw-thread (CST) in crash, the simulationsof frontal crash at the speed of 56 km/h have been carried out in VPG.The peak acceleration in crash has been taken as the evaluation index of energy absorption characteristicsAccording to this function, the best size dimensions of CST in different crash conditions could be easily
