在进行上心盘计算时,边界条件很难正确模拟,本文研究以枕梁(包括心盘座)挠曲变形使上心盘安装面上各点产生的位移,作为边界条件来建立上心盘计算模型,并应用弹塑性有限元理论分析货通上心盘,介绍应用ADINA程序计算上心盘的方法、步骤和应该考虑的问题。
In the calculation of the center of the heart, the boundary conditions are difficult to correctly simulate. In this paper, the bending deformation of the bolster (including the base of the heart plate) is used to make the displacement of each point on the installation surface of the center plate as the boundary condition Calculate the model, and apply the finite element analysis of elasto-plastic finite element theory to the heart of Cathay, and introduce the method, steps and problems that should be considered when applying ADINA program to calculate the heart plate.
