Study of Pre-Tightening Force on Piezoelectric Multi-Dimensional Force Sensor’s Measurement Performance

Abstract:

In this paper, the pre-tightening force on piezoelectric multi-dimensional force sensor is researched. Structure of multi-dimensional force sensor and piezoelectric quartz crystals are introduced and analyzed. The relationship between pre-tightening force and measuring range of force sensor is researched. Structural model of multi-dimensional force sensor is built and analyzed by FEM. Horizontal linearity in horizontal direction with different preloads is obtained. In order to verify FEM analysis, a reduced prototype of piezoelectric multi-dimensional force sensor is fabricated. Verification test is designed and made. The research will provide certain reference value for development of piezoelectric multi-dimensional force sensor.
