【摘要】 选取内燃机配气机构中的关键件———气门,对其失效模式进行了深入研究,建立其有限元模型,进行了应力和强度的分布规律研究,并最终采用商业化的软件进行了可靠度的计算和分析,从而展示结构可靠性分析的方法和分析过程。更多还原

【Abstract】 In this article, we select a valve, which is the key component of diesel, analyze its failure modes and create its finite element models, analyze the distributions of the stress and strength, then calculate the reliability by using commercial software. That presents the method and process of mechanical part reliability.更多还原
