【摘要】 介绍了气缸盖的结构优化过程。针对整机研制中出现的气缸盖故障,进行气缸盖多方案优化设计,并对这些方案进行结构有限元对比分析,确定了一种经优化后的气缸盖主方案,最后利用整机台架试验验证了主方案气缸盖的可靠性。更多还原

【Abstract】 A process of cylinder-head structure optimum is described in this paper. For some cylinder-head mechanical failures happened during the engine development, some optimized designs are submitted and an analysis of these structure designs’ FEM is done. A decision is made to choose the reasonable design. At last the reliability of the chosen design is proved by the engine bench test.更多还原
