Friction Coefficient of Steel on Concrete or Groutdoi:10.1061/(asce)0733-9445(1985)111:3(505)An experimental investigation was conducted to determine the coefficient of static friction between rolled steel plate and cast-in-place concrete or grout.RabbatRussell...
摘要: Experiments were performed to determine the coefficient of friction between concrete and steel. The nominal normal stress varied from 1 P.S.I. to 68,000 P.S.I. The coefficient of friction was found to be nearly constant with an average value of 0.47.关键词:...
the friction force varies continuously so that the notion of a precise coefficient of friction is an approximation to reality, • the calculation of friction coefficient is based on the nominal contact load, i.e.: Frictioncoefficient=Frictionforce/Nominalcontactload In most cases the nominal contac...
Adhesion is a function of the friction at the contact point of wheel/rail—that is, effective tractive effort is the production of the total weight on the drivers multiplied by the coefficient of friction between wheel and rail. The friction or adhesion factor represents the percentage of ...
