This book was released on 1995 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of controlled impact experiments using a charpy pendulum were conducted to address the possibility of dynamic verification and calibration of instrumented tups. The methodology involved striking an instrumented pendulum tup against a rigidly fixtured transducer. The guiding principal is as follows: If a NIST traceable dynamic load cell is impacted by a service load cell, a comparison of the signals can be used to verify the performance of the service load cell. In this fashion, tups can be verified and calibrated electronically, without resorting to the use of standard test specimens. A relatively compliant Nylon bumper was placed between the pendulum tup and the fixed load cells to dampen the excitation of high frequencies during the impact event. During each impact, load-time signals measured by both the pendulum and fixtured tups were recorded, compared and Fourier analyzed. Results of the Fourier analysis justified a simple two-mass-two-spring model of the impact behavior. Results of the experiments are rationalized using the mass-spring model, and present guidelines for designing a verification system for both pendulum and drop-weight testing machines.

Download or read book Impact Tester Compliance written by F. Porro and published by . This book was released on 1990 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The compliance is very sensitive to internal mechanical factors concerning the load system, as the hammer, the tup, the anvils and the base to foundation attachement. In order to verify the sensitivity of compliance measurements, a series of experimental tests has been performed, with artificial and real defect located at the most critical parts. In order to overcame the need of an instrumented impact tester an instrumented specimen has been prepared, together with its electronic system for impact tester compliance measurement. The compliance measurement, after verification of the impact tester with direct and indirect methods, as per ASTM E 23 or ISO R 442, can be helpful for verification of the good working condition of the pendulum and for the detection of onset of anomalies.
