| Research Abstract |
A spring mechanism and some control laws of actuator for vibration isolating bed have been investigated. Firstly, a specification on the transfer characteristics of the vibration isolating bed is determined on the supposition that the acceleration of the bed makes the transported patient's load. Secondarily, some ideal elastic characteristics of the spring are considered. To satisfy the ideal elastic characteristics, a nonlinear spring mechanism employing some pull springs is devised. The full size vibration isolating bed with the nonlinear spring mechanism is designed, and the bed can show possibility of downsizing. Finally, some feedback control laws are examined from viewpoints of magnitude of the control input, sensitivity characteristic, and robustness for disturbances and measured sensor noise. Showing superior performance on the magnitude of the control input and on the sensitivity, the skyhook damper control can be expected to downsize and to have robustness against the weight difference of the trans.
