The shoe-rail resistance to impact of rocket sled was analyzed. Shoe-rail friction resistance was backward calculated with speed, acceleration, weight and gap of shoe-rail. The influencing factor was gain by the continuous contact force model. The relation of shoe-rail resistance to impact with speed, weight and gap of shoe-rail was gained by means of data fitting. Based on the results, the collision resistance coefficient of a new type of sled is calculated. According to the resistance coefficient, the speed of sled is predicted. The predicted results are consistent with the dynamic experimental results.
