BORING BARS OPTIMIZED WITH POLYMER CONCRETE
Jürgen LANG, Paul Dan BRÎNDAŞU, Livia Dana BEJU
Abstract: This paper shows the dynamic properties of steel boring bars modified with the composite material polymer concrete in order to reach good vibration damping during chipping. Polymer concrete has very positive damping properties; therefore the filling out of empty spaces in machine bases as well as the filling out of hollow cavities in civil engineering is a well known application of polymer concrete. On the basis of this knowledge, boring bars with polymer concrete as a supplemental material were manufactured and investigated using theoretical and experimental methods. The modifications of the steel boring bars consist of polymer concrete cores with different diameters in the center of the boring bar. The methods employed in this investigation include the finite element method for static behavior, the experimental modal analysis for dynamic compliance and conclude with chipping experiments.
Key words: tools, boring bar, polymer concrete, vibration damping.
