〔産業上の利用分野〕
本考案は測定具に係り、特に比較的剛性の小さ
いワークの荷重と変位を測定するのに適した荷
重、変位測定具に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a measuring tool, and particularly to a load and displacement measuring tool suitable for measuring the load and displacement of a workpiece with relatively low rigidity.
比較的剛性の大きいワークの荷重と変位を測定

具では荷重と同部位の変位を測定することは出来
ない。
When measuring the load and displacement of a workpiece with relatively high rigidity, a dial gauge is placed on the ram of a hydraulic jack to measure the load and displacement, but when the workpiece has low rigidity, such as urethane foam, is affected by the pressure measurement of the dial gauge, making it impossible to obtain good accuracy. Furthermore, non-contact measuring instruments cannot measure the load and displacement at the same location.
本考案の目的は、剛性の小さいワークの荷重と
変位を同時に高精度で検出し得る荷重、変位測定
具を提供するにある。
An object of the present invention is to provide a load/displacement measuring tool that can simultaneously detect the load and displacement of a workpiece with low rigidity with high accuracy.
