| 摘要 |
An actuator (10, 10′, 10″) is disclosed. The actuator (10, 10′, 10″) is connected to a structural ground (12, 12′, 12″) of a forced oscillation technique device (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000). The actuator (10, 10′, 10″) includes an electrical power source (16, 16′, 16″); a control device (17, 17′, 17″) connected to the electrical power source (16, 16′, 16″); a first portion (14a, 14a′, 14a″) including active material connected to the electrical power source, and a second portion (14b, 14b′, 14b″) including non-active, passive material connected to the first portion (14a, 14a′, 14a″). The first portion (14a, 14a′, 14a″) includes at least one plate-shaped member (18, 18′, 18″). The second portion (14b, 14b′, 14b″) includes a ring member (24, 24′, 24″) connected to and circumscribing a mesh screen (26, 26′, 26″). A forced oscillation technique device (100, 200, 300, 400, 500, 600, 700, 800, 900, 1000) is also disclosed. |
