active structure

Active and passive vibration control integrated theory and technology(IV)-active structure and smart structure;

主、被动振动控制一体化理论及技术(IV)——主动结构和智能结构

By using a 78-bars space truss,the configuration and properties of a linear active structure are studied experimentally,and the experiment technique for constructing an active structure is practiced.

以一个78杆空间桁架为试验模型,研究线性主动结构构型的试验问题。

The basic mode properties of linear active structures with collocated actuator and sensor pairs are presented in the paper.

阐明了传感器和作动器同位配置的线性主动结构模态的基本属性,讨论了同位主动结构在不同反馈率作用下闭环零、极点分布及根轨迹的特点,使用一阶和二阶滤波器对闭环系统进行补偿,使得主动结构获得更大的阻尼和稳定性。

From the contrastive perspective,the author summarizes the active structures of passive meanings and the passive structures of active meanings in English,and illustrates the semantic features both of active structures and of passive structures.

笔者从对比的角度,归纳并分析了英语中的主动结构表示被动意义和被动结构表示主动意义的“倒逆”现象;同时还说明了主动结构和被动结构的语义特征。
