碩士 === 國立臺北科技大學 === 製造科技研究所 === 100 === The structure of the honeycomb panel board because of its special seismic capacity and resistance to impact forces, widely used in engineering. The importance of Sheet metal forming process. In engineering, bending for the common process. This article will explore the honeycomb structural panels of use bending mold to look into the bending feasibility, finite element analysis software LS-DYNA was used to study bending characteristics of honeycomb composite plate. First, the use of analysis software LS-DYNA analysis of the aluminum alloy plate to validate the finite software for bending the accuracy, analysis of the results of the correctness of less than 0.5%. and provides a dynamic parameter as a basis of comparison. After confirm accuracy of analysis, study the bending behavior analysis and simulation of aluminum honeycomb panels with different different thickness height (2mm ~ 8mm). The analysis showed that the forming of the honeycomb structural panels under a certain height can be recognized, but height of more than 6 mm material will be destroyed, beacaue it`s effective stress value exceeds the limit stress value.
