| 摘 要： | It is significant to investigate the landing load suffered by high-level athletes for evaluating the training effect and prevention of injury. Simulation can get the ground reaction force （GRF）that can't be gotten by force platforms，but the accuracy of data needs to be confirmed. The study investigated the similarity and characteristic values of landing force curves got by simulation and force platforms to verify the accuracy and reliability of Lifemod simulation. Results showed that the CMCs of GRF curves gotten by simulation and force platforms were all about 0.90 representing the high correlation. The difference value of maximum GRF was 1.4% of the maximum GRF got by force platforms，and the time difference of getting the maximum GRF was 0.002s.Conclusion：Accurate data matching the real value could be got by simulation. It is feasible and accurate to get the GRF of national level athletes in the training and match.
