| 摘 要： | 应用 Pro/Engineer 三维软件和 I-DEAS 有限元软件对 CY4102BZQ 柴油机缸盖进行实体建模及强度分析计算,得到预紧工况和爆发工况的应力分布图。将有限元计算结果与试验结果相比较,有较好的一致性,证明所建立的缸盖有限元模型正确,计算和试验结果表明气门导管孔周围的应力较大,进而提出原缸盖结构改进方案,并对改进方案模型,进行了强度计算。与原模型对比,整体应力分布有了较大的改善。

| Abstract: | Model of CY4102BZQ diesel head is built with Pro/Engineer 3-D software, and the model into I-DEAS FEA to carry out intension calculation. The results of FEA compared with the test results is imported shows that the finite element model is consistent. The results of calculating and measuring indicate that the stress is big around the valve guides holes. The structure improvement is worked out further and the exact FEA model is bound . Compared with the former model, the whole stress distributing has greatly improved. |
