风洞试验中的压电振动控制
Piezoelectric Vibration Control in Wind Tunnel Tests
摘要
Abstract
In wind tunnel tests,long cantilever stings are usually used to support aerodynamic models. However,this kind of sting support system is prone to vibration problems due to its low damping,which limits the test envelope and affects the data quality. It is shown in many studies that the sting vibration can be effectively reduced by using active sting dampers based on piezoelectric actuators. This paper attempts to review the research progress of piezoelectric vibration control in wind tunnel tests,covering the design of active sting dampers,control methods and wind tunnel applications. First of all,different design schemes of active sting dampers are briefly introduced,along with the vibration damping principle. Then,a comprehensive review of the control methods for active sting dampers is presented,ranging from classic control methods,like PID control algorithm,to various intelligent control methods. Furthermore,the applications of active sting dampers and controllers in different wind tunnels are summarized to evaluate their vibration damping effect. Finally, the remaining problems that need to be solved in the future development of piezoelectric vibration control in wind tunnel tests are discussed.关键词
