Development of Three-Dimensional Force Measurement Instrument Using Zero-Compliance Mechanism

摘要

A three-dimensional force measurement instrument is designed and developed by considering the basic principle of zero compliance mechanism. In the proposed system, the point of force and the detection point are connected in series and suspended with leaf springs. One of the suspensions operates to cancel the displacement of the other. If any force is applied at point of force that causes displacement, the detection point displaces proportionally to cancel out the displacement of the point of force. As a result, zero compliance is achieved at the point of force and applied force can be measured from the displacement of the detection point. This paper presents the design and construction of a three-dimensional force measurement instrument and the effectiveness of the proposed system is demonstrated by the experimental result of the vertical-direction force measurement.
