Description
技术领域
本发明专利涉及一种泡沫铝芯三明治板材冲压成形界面抗剥离性能检测方法。
背景技术
泡沫铝芯三明治板材零件是一种新型功能零件,具有许多独特性能。如:高比强度、高比刚度、吸声、隔声、隔热、阻燃、减振、吸收冲击能、电磁屏蔽等多种物理性能。在汽车工业、建筑业、化工业、航空航天业、船舶、兵器等领域具有广泛的应用前景。
泡沫铝芯三明治板材冲压成形时经常产生诸如面板与泡沫芯间界面脱离,严重制约三明治板材冲压极限的提高。因此,研究界面剥离机制及控制措施对于提高泡沫铝芯三明治板材冲压成形极限具有重要意义。
本发明主要是为泡沫铝芯三明治板材冲压成形抗剥离性能提供一种简单易行的检测方法,为大规模制备实用于冲压成形泡沫铝芯三明治板材零件提供技术保障。
发明内容
为了快速冲压成形制备泡沫铝芯三明治板材零件,本发明专利提供一种检测其界面抗剥离性能的方法。
为实现上述目的,本发明采用如下的技术方案是:一种泡沫铝芯三明治板材冲压成形界面抗剥离性能检测方法,其内容如下:
研究了泡沫铝芯三明治板材V型弯曲过程,建立冲压弯曲试验系统。综合运用试验、塑性力学理论分析研究方法,研究了泡沫铝芯三明治板材冲压界面剪切应变和界面剥离机制,为界面剥离冲压缺陷控制及三明治板材冲压性能评估奠定了基础。

具体实施方法
本发明关于一种泡沫铝芯三明治板材冲压成形界面抗剥离性能检测方法,其具体实施步骤包括:利用图1所示为试验样件和V型90°直角实验装置进行冲压实验。将三明治板材切割成所需尺寸的板条毛坯,用于弯曲成形。
见图1所示,当冲压深度(h)达到一定数值时,由于上、下板面及泡孔间发生严重的不均匀变形,弯矩诱发铝芯和面板间剪切应变,剪切应变达到一定程度时发生界面剥离。通过测量冲压深度(h)数值,建立各种类型泡沫铝芯三明治板材的冲压成型界面抗剥离性能的冲压深度数值表,检测其界面抗剥离性能。
以上实施方式仅仅是对本发明的优选实施方式进行描述,并非对本发明的范围进行限定,在不脱离本发明设计精神的前提下,本领域普通工程技术人员对本发明的技术方案做出的各种变形和改进,均应落入本发明的权利要求书确定的保护范围内。
