Abstract:
Purpose. Development of a wheel pair with wheels that provide protection against derailment due to counter-flanges and substantiation of efficiency of its applying at mining transport.
Methodology. Mathematical and simulation modelling of geometric, friction and dynamic parameters of contact interaction between the wheel and rail of the proposed wheel pair by applying difference equations, elements of theoretical mechanics, mechanical system dynamics, analytical geometry, etc.
Findings. The authors have proposed scientifically grounded engineering solution for designing the wheel pair that has wheels with counter-flange which satisfies the existing standards of vertical and horizontal dynamics and movement stability index. Results of calculations for coefficients of dynamics and transverse stability for the wheel pair with wheels that have counter-flange are the same as computational data for freight cars with all-rolled wheels over the range of 10–15 % and no more than standard values.
Improved contour of the rail wheel with counter-flange has been developed. It provides the additional contact in horizontal plane while transverse vibrations of the wheel pair relative to rail track and makes carriage more stable and increase the resisting force of the wheel against derailment when passing curved section of line.
Originality. Methods for creating working contour of wheels for special-purpose rolling stock that takes into consideration counter-flange at the rolling surface were further developed. Force interaction patterns of wheel pair with wheels that have counter-flange and side edge of rail top have been obtained for the first time. Relation that describes the influence of transverse force during performance of car on curves at contact of wheel with counter-flange with rail.
Practical value. The authors have developed a wheel pair for mining transport whose contour has the additional running track and counter-flange that protects against derailment when base flange of wheel rolls in working surface of rail or there is way spacer due to rail elastic deformation. The wheel pair design suggested is covered by Ukrainian patents for utility modal.
