摘要： PROBLEM TO BE SOLVED: To provide a semiactive isolation system with a variable structure capable of taking a time lag of a variable damper into account and improving robustness for controlling performance on a structure as a control target and a modeling error of the variable damper.
SOLUTION: The semiactive isolation system provides the variable damper 4 arranged between upper and lower structures 1 and 2 of an isolated structure, sensors 5a for sensing responses of the upper and lower structures, a control means 6 with a computer 8 for calculating and outputting command signals to the variable damper on the basis of the sensed signals, and a switching means 7 for switching damping force by means of the command signals. The computer 8 adopts an adjustable structure control method for controlling response deformation and/or response acceleration by switching a damping coefficient of the variable damper on the basis of a switching hyperplane as a control regulation calculated by a bilinear optimal control theory in a state of the equation of an isolated structure against a state equation of a whole system which combines a relational equation between a damping force setting value of the variable damper and actually generated damping force.

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic shock absorber monitoring system monitoring existence of abnormality of an electromagnetic valve of a hydraulic shock absorber. SOLUTION: The hydraulic shock absorber monitoring system 10 is assembled in an isolation system which isolates vibration of a structure such as a high-rise building. A control circuit 50 of the hydraulic shock absorber monitoring system 10 analyzes vibrating conditions of the structure from detected signals in response to output acceleration of first to third acceleration sensors 42, 44, and 46, and produces control signals to hydraulic shock absorbers 20(20 1 to 20 10 ) so as to produce damping force suitable to the vibrating conditions, and adjusts damping coefficients of the hydraulic shock absorbers 20(20 1 to 20 10 ). Further, the control circuit 50 determines whether or not a current detecting value detected by the sensors for detecting a current of a signal supplying to the electromagnetic valve 96 of a damping force adjusting section is normal. Thus, the control circuit 50 can monitor whether or not any electromagnetic valve 96 is normal by operating numerous electromagnetic valves 96. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To realize the measurement having high reliability which is stable for a long period of time, by eliminating unstable factors in the measurement, such as shift in the zero point of a measured value and so forth, in which the zero point of a load transducer can be managed, using a simple constitution and an operation. SOLUTION: When an oil which is pressurized and sent from an oil pump prepared separately is introduced to a cylinder room 8 via an oil pressure inlet part 4c, a movable member 5 is moved upward. At the end region of the moving process, a push out part 5c of the movable member 5 pushs an upper pedestal 13 out, and an upper pedestal 2 finally rises up from the upper surface of the load transducer 3. The load transducer is in the load-free state, and the output thereof is at the minimum. Although it is not shown, a switch for detecting the load-free state is off, and the measured value at that time is set as the load zero. COPYRIGHT: (C)2004,JPO
