Research and Development of Automatic Stiffness Measuring System for Torsion Bar

Aimed at the measuring of torsion bar's stiffness,a sort of fire-new dynamic measuring method-self-excitation dynamic tiny-sway method is proposed.This method uses positive feedback control to let torsion bar self-excitation,then by measuring torsion pendulum system's nature frequency to calculate torsion bar's stiffness.By analyzing the torsion pendulum system's work theory and automatic measuring method,a suit of automatic stiffness measuring system for torsion bar is developed,which realizes torsion bar's automatic measur- ing,resolves the difficulty in the torsion bar's production process,improves torsion bar's production efficiency,satisfies torsion bar's passel production request.
