| 摘 要： | 提出了一种基于静电驱动的新型机电集成传动系统,描述了该传动系统的基本工作原理.用Fourier级数形式表示了静电场力的动态分量和3个模态函数,在Donnell壳理论的基础上建立了电场力作用下系统的动力学模型.借助内力和位移的关系式,并运用边界条件,得出了一端自由一端固定柔轮的频率方程,用数值算例证实了算法的收敛性,讨论了振动频率随主要参数的变化规律.将所得若干频率值与ANSYS的仿真值进行比较,验证了该方法的准确性.所述方法为进一步研究该种传动的更多动力学特性提供了有益参考.

| Abstract: | A novel electromechanical integrated drive system actuated by electrostatic force was proposed,the basic operating principle of which was also described.The dynamic component of electrostatic force and three modal functions were represented in Fourier series form.The dynamic model for the drive system subjected to the electrostatic force was established on the basis of Donnell's shell theory.Using the relationships between internal forces and displacements,and considering the boundary conditions,the frequen... |
