Abstract ： In order to improve the efficiency of finite element modeling ofbones and reduce simulation solving time，this paper takes the human femur as an example to explore a modeling simplification method based on three-point bending experiments.Firstly，a femur model was constructed using traditional modeling methods， andits feasibility was verified by comparing the resultsof three-point bending simulation with cadaver experiments. Subsequently，use the warp and global commands to generate two simplified models respectively， and conduct three-point bending simulation tests on the three models.The results indicate that although the warp method hashigh modeling efficiency，the solving speed is still not ideal.In contrast，models built using the global command not only model quickly but also have the shortest solution time，significantly reducing computational costswhile maintaining simulation accuracy.This method provides an efficient and practical simplification solution for bone modeling.
