Objective The finite element pelvis model with detailed anatomical structures which meets the Chinese human 95th percentile characteristics is developed, and the influence of cortical bone modeling methods on the biomechanical response of the real pelvis is explored. Methods Based on the pelvic medical images of a 95th percentile male volunteer, the two finite element pelvis models with real hip bone cortical bone thickness (REA-M) and 2 mm uniform cortical bone thickness (CON-M) dominated by hexahedral elements were constructed. Using simulation methods to reconstruct the loading conditions of cadaver experiments, the validation of models was verified by comparing the experimental results and simulation results, and biomechanical response differences of the two models under different working conditions were discussed. Results The simulation data showed that there was a strong correlation between overall biomechanical responses of the two pelvic models and the cadaver experiment, and the mechanical response difference between the two models was mostly within 8%, and the correlation score difference between the two models was smllaer than 2%. Conclusions The validation of the two pelvic models established in this study is verified by rebuilding multiple simulation experiments. Although biomechanical responses of the two models are different, the difference in the mechanical responses of CON-M and REA-M models were small. From the perspective of model simplification, the CON-M model can be used to study the biomechanical response of the pelvis.
