Apparatus and Method for Measuring Fixing Force

摘要

A fixing force measuring apparatus including a section for applying a predetermined controlled hammering force to a wedge surface to generate a hammering sound, a section for controlling the hammering sound generated, a section for obtaining plural kinds of feature quantities such as a feature quantity due to a hammering sound energy, and a feature quantity due to a frequency of the hammering sound from the hammering sound collected by an arithmetic operation, and a section for obtaining a fixing force corresponding to the plural kinds of feature quantities by using a correlative relationship between the wedge fixing force previously obtained, and the plural kinds of feature quantities.

主权项

1. An apparatus for measuring a fixing force of a plate-like member, comprising:
means for applying a predetermined controlled hitting force to a surface of said plate-like member to generate a hitting sound; means for collecting the hitting sound generated; means for obtaining plural kinds of feature quantities from the hitting sound; and fixing force estimating means for estimating the fixing force from a database representing a relationship between the plural kinds of feature quantities previously prepared in correspondence to a kind of evaluation object, and the fixing force, and the feature quantities extracted from said database and the hitting sound.
