摘要
金属膜片贮箱中,膜片工作过程的设计计算至关重要,其翻转过程涉及到材料非线性、几何非线性等强非线性因素,传统的解析方法难以完成这样的计算。采用大变形弹塑性有限元法,用MSC.MARC软件对膜片的变形进行数值仿真,实现了膜片的翻转计算。膜片的翻转试验表明,数值仿真与试验结果吻合较好,分析方法合理可行。
Calculation for metal diaphragm overturning process is the key factor for diaphragm tank design, in which strong nonlinearity factors of material, geometry, etc. should be considered. It＇s hard to complete such a complicated calculation with traditional methods. Diaphragm overturning process calculation was accomplished by employing MSC.MARC software with elastic-plastic finite element method. Test results fit the digital simulation very well which proved the validity of the analysis approach.
