Study on the Calculating Method of Anti-slipping/sliding Efficiency Based on Wheel-rail Tangential Force
After completing the anti-slipping/sliding test on a metro car,the anti-slipping/sliding performance of the car is generally evaluated by calculating the anti-slipping/sliding efficiency.At present,there isn't a unified method for calculating the anti-slipping/sliding efficiency of metro car.To solve this problem,this article introduces the wheel-rail adhesion mechanism and property,compares and analyzes the existing adhesion control strategies and calculating methods of anti-slipping/sliding efficiency of vehicles,establishes a mechanical model in traction and braking conditions of vehicles and proposes a calculating method of anti-slipping/sliding efficiency based on wheel-rail tangential force.Compared with existing calculating methods of anti-slipping/sliding efficiency,this method is applicable to the calculation of efficiency in both anti-slipping test and anti-sliding test,excluding the impact of car operation resistances on the calculated result and having a better consistence among the calculated results in different test conditions.
