以新型凸轮机构为研究对象,首次提出“弹簧工作始点”的概念,发现其“上确界”的客观存在性,揭示出弹簧刚度系数随“弹簧工作始点”的变化规律。文中的研究结论对力锁合弹簧“预紧性设计”的传统认知作法具有一定的冲击性和颠覆性。
Taking the new type of cam mechanism as the research object, the concept of “starting point of spring work” was first put forward and the objective existence of “exactitude ” was found. The variation law of spring stiffness coefficient with the “spring starting point” was revealed . The conclusion of the paper has a certain impact and disruption on the traditional cognition of force locking spring “precontractive design ”.
