| 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。

| Abstract: | 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. |
