%0 Journal Article %T Investigation of the influence of friction pairs geometrical parameters of wagon truck spring - frictional set on the effectiveness of their operation %A Khabibulla TURANOV %A Oleg CHEREPOV %A Kamoliddin IRGASHEV %J Transport Problems : an International Scientific Journal %D 2011 %I Silesian University of Technology %X The article gives an account of the results of the analytical and numerical modeling of force action of friction pairs ¡°truck bolster ¨C frictional wedge¡± and ¡°frictional wedge ¨C frictional plank¡±. There have been obtained formulas for determining con-straint reactions according to friction pairs geometrical parameters which makes it possible to find their rational values. %K spring-frictional complete set %K friction pair %K reactions of constraint %K tilt angles of contacting surfaces %U http://transportproblems.polsl.pl/pl/Archiwum/2011/zeszyt1/2011t6z1_08.pdf
