Control, automated torsion pendulum

Automated Torsion Pendulum Control and Data Collection/Reduction Using a Desktop Computer... [Pg.329]

The purpose of this paper is to describe an automated torsion pendulum controlled by a desktop computer, to discuss four separate methods of data analysis, and to compare the results of a torsion pendulum experiment and a TBA experiment using the same epoxy resin. [Pg.330]

Figure 4. Automated torsion pendulum control sequence. Key 1, previous wave decays, drift detected and correction begins II, reference level of polarizer pair reached III, wave initiating sequence begins. IV, decay of transients V, free oscillations begin VI, data collected and VII, control sequence repeated. Figure 4. Automated torsion pendulum control sequence.

A torsion pendulum interfaced with a desktop computer form an automated instrument for dynamic mechanical characterization of polymeric materials. The computer controls the initiation of the oscillations, collects the digitized data and calculates the shear modulus and loss modulus from the damped oscillations, utilizing one of four methods of analysis ... [Pg.329]
