ANALYSIS DEVICE, ANALYSIS METHOD AND RECORDING MEDIUM

Document Type and Number:

WIPO Patent Application WO/2015/083429

Kind Code:

A1

Abstract:

[Problem] To provide a simpler device configuration for analyzing contact phenomena between objects. [Solution] Provided is an analysis device which is provided with: an acquisition unit which acquires vibration data indicating the vibration generated in a first object through contact by a second object at a first position on the first object; a first analysis processing unit which specifies a first position by comparing the vibration properties indicated by the aforementioned vibration data and vibration properties defined for each position on the first object where the second object might have made contact; and a second analysis processing unit which estimates the speed of the second object after the contact on the basis of the speed of the first object and the first position.
