| 摘 要： | 直升机振动主动控制通常使用惯性作动器,一般惯性作动器的附加重量要占到机体重量的4％～5％才有较好的控制效果.压电叠层作动器(PSA)作为轻质、高效的执行元件用于直升机振动主动控制可有效地降低附加重量、提高控制性能.本文将压电叠层作动器用于直升机振动主动控制,并提出了机身/压电叠层作动器耦合优化法.采用基于频率响应函数的...

| Abstract: | Inertial actuators are usually used in active vibration control of helicopter,additional weight of which generally has to account for 4%-5% of fuselage weight to achieve satisfactory control effect.This paper proposes the use of light-weight piezoelectric stack actuators(PSA) for active vibration control of helicopter to reduce additional weight,and presentes a coupled fuselage/piezoelectric stack actuator optimization method.By using the sub-structure method based on frequency response functions,the couple... |
