Title:
ACTIVE VIBRATING TABLE
Document Type and Number:
Japanese Patent JP3876084
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a vibrating table capable of comparatively simply realizing improvement of capability of a vibrating table without adding any means to conventional vibrating table control system.
SOLUTION: This active vibrating table includes a vibrating table 1, a specimen 2, an acceleration sensor 3, a distortion gauge 4, an inertia mass 5, a first actuator 11, a first controller 21, a second actuator 12 and a second controller 22, where the specimen 2, the acceleration sensor 3 and the inertia mass 5 are mounted on the vibrating table 1, the actuator 12 is mounted between the inertia mass 5 movably mounted on the vibrating table 1 and the vibrating table 1, the distortion gauge 4 is installed between the specimen 2 and the vibrating table 1, the actuator 11 is installed between the vibrating table 1 and a fixed object 9 on the ground, the controller 21 receives a signal inputted from the acceleration sensor 3 to output a control signal to the actuator 11, and the controller 22 receives a signal input from the distortion gauge 4 to output a control signal to the actuator 12.
