Title:
VIBRATION SIMULATION METHOD OF BODY IN FLUID AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP3842126
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To measure accurately a fluid pressure working on a model when an object is vibrated by receiving the pressure from the fluid, and to simulate precisely the vibration state of the model in the fluid by removing the influence of an inertia force at the excitation time of the model.
SOLUTION: This device is equipped with a fixed pedestal 11, a gimbal 12 mounted on the fixed pedestal 11 rotatably around the X-axis, a support 13 connected to a lower part of the gimbal 12, the model 14 connected to an upper part of the gimbal 12, and pressure-tube anemometers 15a, 15b disposed on the wall faces on the front face 14a side and the rear face 14b side of the model 14. The model 14 is vibrated, and wind pressures (fluid pressures) working on the front face 14a and the rear face 14b of the model 14 are measured simultaneously by the pressure-tube anemometers 15a, 15b. A response value X of the model 14 by the measured wind pressures is processed by a computer 24, and feedback thereof to an excitation means 20 is performed to vibrate the model 14, to thereby realize in real time, vibration state of the model 14.
