RT Journal Article SR Electronic A1 Lack, Tomas A1 Gerlici, Juraj T1 The Usage of Arcs Radii Profile Variation for the Synthesis of Railway Wheel and Rail Head Profiles JF Communications - Scientific Letters of the University of Zilina YR 2006 VO 8 IS 2 SP 59 OP 69 DO 10.26552/com.C.2006.2.59-69 UL https://komunikacie.uniza.sk/artkey/csl-200602-0008.php AB The presented article deals with one of the ways of profile geometry design of a railway wheel and railhead. The base for the creation of new profiles is an interactive attitude based on the modification of "the original shape which is defined by section of a railway wheel profile", with to each other connected and exactly defined arcs radii. It is possible to change them according to shape needs of the final geometrical characteristics.
