The invention provides a wheel-rail contact point calculation method. The wheel-rail contact point calculation method comprises the following steps: S1, selecting a wheel-rail local coordinate system and a wheel-rail global coordinate system; s2, selecting a wheel set posture description mode; s3, carrying out segmented fitting on profiles of the wheels and the steel rails; s4, calculating the penetration amount of the profile of the wheel track; and S5, the wheel-rail contact point position is obtained, and Euler parameters are adopted in the step S2. According to the method, a technical route of a trace method based on profile fitting is adopted, Euler angles are replaced by Euler parameters in a wheel set attitude description mode selection link, the universality of attitude description of a wheel-rail contact point solving algorithm is improved, the problem of singularity of the Euler angles is solved, and the method can be conveniently integrated into multi-body dynamics solving.
