Electro-Hydraulic Shaking Machine : Report 3. Influences of Oscillatory Test Structure and Their Compensation

抄録

In this paper, control characteristics of a shaking machine under the influences of an oscillatory test structure are discussed. In addition, it is shown that the influences of the oscillatory test structure can be compensated by feeding back the relative acceleration, velocity and displacement between the shaking table and the test structure with proper gain rate. The effect of this compensation method is confirmed experimentally with a shaking machine which has a one ton table.
