采用弹性接触的有限元模型，对移动心盘进行了强度及刚度的数值分析，在给出了对原结构的分析结果之后，提出了优化设计方案，经计算后证明这一优化过程是行之有效的。 The finite element model of elastic contact was used to analyze the strength and stiffness of the moving heart plate. After giving the analysis results of the original structure, an optimized design scheme was proposed, which was proved to be correct after calculation Effective.
