<p>PROBLEM TO BE SOLVED: To test a part other than a vibration control device serving as a vibration test evaluation target as a practical sample.SOLUTION: Provided is a vibration testing apparatus 100 comprising: a first vibration test mechanism 10 displacing a first vibration table on which a vibration control device is installed; a second vibration test mechanism 20 displacing a second vibration table on which a sample is installed; an arithmetic unit 30 computing a numerical model simulating a structure to which a seismic wave is input; a control unit 40 controlling the first vibration test mechanism 10 on the basis of a first displacement command value d1, and controlling the second vibration test mechanism 20 on the basis of a second displacement command value d2; a first load detector 50 detecting a first load acting on the first vibration table by the vibration control device; and a second load detector 60 detecting a second load acting on the second vibration table by the sample, the arithmetic unit 30 generating the first displacement command value d1 and the second displacement command value d2 on the basis of the input seismic wave, the first load, and the second load.</p> |
