Title:
VIBRATION TEST DEVICE, VIBRATION TEST METHOD, AND PROGRAM
Document Type and Number:
Japanese Patent JP2021179362
Kind Code:
A
Abstract:
To provide a vibration test device, a vibration test method, and a program that are able to easily control excitation force of a vibration exciter.SOLUTION: A vibration test device includes: a detection unit that detects a drive current supplied to a conductive type of vibration exciter; and a control unit that vibrates the vibration exciter by supplying the drive current to the vibration exciter. The control unit acquires a detection value of a first drive current, which is the drive current detected by the detection unit when the vibration exciter with a test-piece loaded thereon is vibrated and a detection value of a second drive current, which is the drive current detected by the detection unit when the vibration exciter with the test-piece unloaded is vibrated, calculates a difference value between the acquired detection values of the first drive current and the second drive current, and adjusts the drive current based on the calculated difference value, thereby controlling exciting force of the vibration exciter.SELECTED DRAWING: Figure 1
