摘要
推导了三角形夹芯板夹心层的等效弹性常数,为验证所推导的弹性常数的合理性,用NASTRAN有限元计算程序对两种模型进行了静力计算比较,一种是用所推导的弹性常数将夹心等效后,以层合板的形式进行计算的模型,另一种是对整个结构直接采用板单元进行计算的模型.计算结果表明:两种模型结果吻合良好.
The equivalent elastic coustants of the truss-core sandwith plates are derived. To verify the correction of these equivalent elastic constants, linear static analysis of an aluminum sandwich plate under pressure out of panel was performed with NASTRAN program. Results of equivalent laminate plates FE analysis are in good agreement with results of FE analysis using shell elements.
