National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Study of the Interactions Between Friction, Wear and System Rigidity. Progress Report, July 1, 1979-June 30, 1980.

Abstract	Progress in friction and wear studies is reported. After an extensive study of various possible systems for friction, wear and vibration measurements, a pin and disk sliding system has been designed to be used on a rigid lathe bed. This versatile design has the capability of controlling the applied load, rigidity and damping of the total frictional system. The design and construction of the pin holding assembly has been completed with certain features to render it suitable for acquisition of appropriate data such as forces and displacements. Special instrumentation has been obtained the major components of which are a tri-axial quartz piezoelectric force transducer, a tri-axial ceramic piezoelectric accelerometer for measurements of vibrations of the slider, charge preamplifiers with dc power supply, and monitoring equipment such as a spectral analyzer and an oscillograph. Preliminary experiments indicate that the system, as designed and constructed, is appropriate for the type of study undertaken in this project. Some preliminary experimental results are included here. The method of describing functions and harmonic balance is being employed for the study of friction induced self-excited vibrations. Some new developments of this method have been obtained to take into account the coupling between the degrees of freedom in the normal and frictional directions. (ERA citation 05:024509)
