新型压电行走机构振动模态的有限元分析
Finite Element Analysis of Vibration Modal of a New Type of Piezoelectric Walking Mechanism
摘要
Abstract
Excited by alternative current, the piezoelectric patch on the piezoelectric walking mechanism will vi- brate and makes the feet of the piezoelectric walking mechanism produce local elliptical motion. In order to analyze the relationship between the frequency of excitation signal and mechanism moving states, such as moving forward, moving backward, left-handed rotation, right-handed rotation, and to control mechanism moving states precisely, a new type of piezoelectric walking mechanism was proposed based on the working principle of structure. Modal anal- ysis and response analysis of the vibration component of mechanism was carried out using finite element analysis software. The analysis of the relationship between vibration modal and moving states explained why the machine moved backward.关键词
