Based on the multi-body dynamics software SIMPACK, a vehicle-track dynamics model on heavy haul railway is established. And effects of curve radius and superelevation on wheel-rail dynamics performance are analyzed by the model. The results show that wheel-rail dynamics performance is improved with the increase of curve radius of heavy haul railway, but it is improved to a lesser extent when curve radius is over 800 m. And wheel-rail dynamics performance will be decreased when the superelevation on curve is excessive or inadequate. So deficient superelevation is advantageous for improving the wheel-rail dynamics performance and the reasonable superelevation is recommended to decrease 5% to 10% of balanced superelevation.
