摘要
为了研究装订机精冲板的可靠性,采用有限元和蒙特卡洛相结合的方法对装订机精冲板模型进行了500次的模拟抽样,并对其刚度和强度的可靠度及灵敏度进行了分析。计算结果表明,除了材料的随机因素外,影响最大的因素是第9个孔上的载荷和精冲板厚度,这对装订机精冲板的可靠性优化和制造过程中提高其可靠度提供了依据。
Aiming at the study of the reliability for punch-board model of binding machine,finite element and Monte-Carlo method were adopted to stimulate and 500 times samplings were carried on,and then the reliability and sensitivity of its stiffness and strength were analyzed.The results indicate that,except the random elements of material,the most influential elements are the load of the ninth hole and the thickness of the punch-board.It will provide the necessary evidence for improving its reliabilty during its optimization and manufacturing stage.
