Design of Multi-Channel Signal Acquisition System of the Torsion Spring Based on LabVIEW

This paper presents a torsion spring detection and analysis system which is different from traditional torsion spring detector. The design is based on virtual instrument software with multi-channel signal acquisition. Two characteristic quantities, torsion angle and the torque, are collected and will be analyzed and processed by the computer, which owns large storage capacity and strong analyze ability, to store and display the data as the format of two dimensional graph.
