摘要： PROBLEM TO BE SOLVED: To provide an apparatus and a method, for the vibration test of a vehicle, wherein a target waveform is generated quickly and with high accuracy and various tests can be performed in a short period. SOLUTION: Target waves corresponding to the displacement in the vertical direction of a road-surface wave element are expressed by YT(t). Input waves which are input to an exciter are expressed by Xn(t) as nth-order compensation waves. Nth-order output waves which are output by the exciter are expressed by Yn(t). Xn is a function which is described by a linear combination on the basis of a first term containing Xn-1 and on the basis of a second term expressed by YT and Yn-1. A control signal based on two pieces of information on the target waves YT(t) and the output waves Yn(t) is combined with the input waves Xn(t), and especially a control signal by the linear combination is used repeatedly several times. Therefore, a plurality of motions in the vertical direction of a plurality of wheels in which action faces subjected intermittently and in parallel are physically influenced can be brought close to a target value quickly and asymptotically.

摘要： PROBLEM TO BE SOLVED: To reduce redundant navigation of a submarine when correcting the present position of the submersible vessel to conduct updating processing (position updating processing). SOLUTION: The submarine 10 sails underwater toward a transponder provided in an underwater prescribed position. An inertial navigation system 11 estimates the present position 6 of the submersible vessel 10 based on the position in the past of the submersible vessel 10. A position measuring instrument 12 executes a searching operation for the transponder in the first point where the submersible vessel 10 is separated by the first searching distance from the transponder, in order to execute the position updating processing. The redundant navigation of the submersible vessel 10 is reduced by the searching operation of the transponder, in the present invention. The position measuring instrument 12 measures a direction of the transponder with respect to an advancing direction of the submersible vessel 10, and a distance from the submersible vessel 10 to the transponder, based on a result of the searching operation by the transponder, and corrects the present position 6 of the submersible vessel 10 based on the direction and the distance. The inertial navigation system 11 accurately updates thereby the present position of the submersible vessel 10. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To set a compensating velocity more properly while making it possible to easily set the compensating velocity, thereby enhancing the accuracy of computations needed for setting the compensating velocity. SOLUTION: This velocity controller for a vehicle collision testing apparatus controls a vehicle velocity at a releasing point P to a velocity equal to a desired collision velocity Vcr plus a compensating velocity Vα so that a vehicle velocity at the collision of the vehicle attains the desired collision velocity Vcr. Using a travel resistance dependent parameter which a compensating velocity setting part 24 for setting the compensating velocity Vα detects while the vehicle is being run during a vehicle collision test, Coulomb's friction not depending on the vehicle velocity, viscous friction proportional to the vehicle velocity, and air resistance proportional to the square of the vehicle velocity are estimated, and the compensating velocity Vα is set by use of the Coulomb's friction, the viscous friction and the air resistance.

摘要： PROBLEM TO BE SOLVED: To calculate the center-of-gravity position of a object by determining the inertial moment around each axis in an optionally set the remarked point of the object, determining the mass, the coordinate in the remarked point, and the difference in inertial moment of the object between the origin and the remarked point. SOLUTION: A table and a sample 5 are excited by a plurality of servo valves 3 and an exciter 4, and the servo valves 3 and the exciter 4 are controlled by a controller 2 according to the output values of the target posture setter 1 and a mass characteristic estimating device 6. A remarked point is set in an optional point of an object different from the origin, and the mass characteristic estimating device 6 calculates the mass, inertial moment and center-of-gravity position of a load required in the controller from the output value of the table acceleration sensor 22 mounted on the table and sample 5 and the coordinate value of a remarked point A coordinate setter 7, and output them to the controller 2. Thus, by utilizing that the inertial moments around different points are differed depending on the distance from the center of gravity, the difference in inertial moment between two remarked points is determined to estimate the center-of-gravity position.

摘要： PROBLEM TO BE SOLVED: To enable one storage battery to avoid lack of electricity in being used outside a facility of a power supply target, while supplying power to a power load in the facility.SOLUTION: A state of charge prediction calculation unit calculates a state of charge of a storage battery at each time point on the basis of planned use outside a facility, predicted power consumption, and predicted generated power. A maximum state of charge adjustment unit plans to charge the storage battery using external supply power in a time zone where a power rate is relatively low, so that a maximum value of obtained states of charge at respective time points becomes a predetermined state of charge maximum value. An outside facility use time state of charge adjustment unit plans to charge/discharge the storage battery so that an outside facility use end time state of charge, which is a state of charge of the storage battery at outside facility use end planned time, becomes equal to or larger than a predetermined state of charge minimum value. A charge/discharge control unit controls charge/discharge of the storage battery on the basis of the obtained plans.

摘要： PROBLEM TO BE SOLVED: To provide a position updating method capable of updating position information having smaller error. SOLUTION: A submarine boat 10 is provided with an inertia navigation device 11, a position measuring device 12, and a display device 16. The inertia navigation device 11 has position information 6 indicating a position of the submarine boat 10 and calculates a position of the submarine boat 10 based on angular velocity when the submarine boat 10 runs in the water to generate calculation results. The position measuring device 12 measures a position of the submarine boat 10 for a first transponder by Nth time (N is a positive number above 1) to generate measurement results by the number of N. The position measuring device 12 compensates the calculation results based on the number of N of the measurement results to control the inertia navigation device 11 so that the position information 6 is updated using the compensated calculation results as the position information 6. The position measuring device 12 controls the display device 16 so as to display the position information 6 updated by the inertia navigation device 11. COPYRIGHT: (C)2003,JPO
