| 摘 要： | 仿生微扑翼飞行器的翅翼具有较大的柔性,并有较大的变形.寻求一种翅翼动力分析的方便、有效的方法是翅翼机构设计和分析的关键问题之一.将有限刚体元(Rigid Finite Element)方法应用于翅翼的动力分析,包括一般有限刚体元方法和改进的有限刚体元方法.研究表明,当翅翼的分段数目达到一定数目的时候,有限刚体元方法的计算结果与采用有限元方法的计算结果相差不大,而前者具有简单、方便、省时的优点.

| Abstract: | The insectlike flapping wing should be flexible link with larger deformation.The dynamic-motion analysis of such link is the key issue for the design and analysis of a flapping-wing mechanism.In this paper,the rigid finite element method is employed,in both the general and modified forms.It is shown that the results produced from the rigid finite element method are almost same as that produced from finite element provided that the flexible link is divided into some numbers of rigid elements.But the rigid fi... |
