衝撃荷重測定のためのYANAGIHARA短棒法

抄録

This paper presents a method for measuring the correct impact force acting on the top of a short bar. In this method, the impact force is calculated from the stress detected by the strain gauge at one point on the short bar. The theory of this measuring method based on the theory of propagation of longitudinal elastic stress wave is very simple. It is confirmed by the impact test that this measuring method is suitable in practical use. This method can be applied to the measurement of force in the range from impact to quasi-static force.
