Title:
SYSTEM FOR ESTIMATING REACTION FORCE OF TEST BODY
Document Type and Number:
Japanese Patent JP3843108
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a test body reaction force estimating device capable of estimating reaction force of a testing body, based on known data such as vibration table oscillation force, without measuring directly a reaction force value of the test body.
SOLUTION: Coordinates are transformed from a vibration table coordinate system into an absolute coordinate system, as to the oscillation force of an oscillator 3 for oscillating a vibration table 2, the oscillation force applied onto the vibration table 2 is found based thereon, inertia force of the vibration table 2 is found from a mass and an acceleration of the vibration table 2, and the reaction force from a test body model 1 laid on the vibration table 2 is estimated based on a difference between the found oscillation force applied onto the vibration table 2 and the inertia force of the vibration table 2.
