Driving force of wheel on soft lunar soil is much different with wheel on the ground of the earth.Wheel sinks and slides easily on lunar soil.The driving force formula of wheel based on Bekker formula is much complex,for forecasting driving force,curve fitting based on least squares method was introduced to simplify formula driving force.The driving force can be calculated through measuring wheel sinkage and slide.

In addition, total wheel/rail contact calculation with divided rail outline method are raised. Under the condition of considering the displacement, bouncing, yaw, roll of wheelsets and displacement, bouncing, roll of rails, minimum gap between rail and wheel were calculated by the trochoid method and divided rail outline method, we can easily judge totally real contact states of the wheel/rail such as normal one-point contact, nonnormal one-point contact, two-point contact and wheel complete lift. Wheel/rail normal forces in the two contact point are respectively calculated by nonlinear Hertz contact theory, and then, result of simulation more close to reality on actual track.
