In order to analyze the performance of different footwear midsole structures based on foot biomechanics,three foot contact simulation models based on finite element simulation were established to simulate and predict the plantar pressure and bone stress distribution caused by wearing different footwear midsole structures.The thin-slice CT scanning is performed on a sub-jects's right foot to obtain Dicom data.In order to obtain a complete and clear geometric model of the foot,the 3D reconstruction software Mimics 21.0 and reverse engineering software Geomagic Design X are imported for optimization processing.The foot geometric model is meshed by Hypermesh and imported into Marc for static numerical analysis.The validity of the finite element model is proved by compressive experiment and simulation of chiral.Simulation results show that part of the plantar pressure is transferred from the heel to the arch in chiral,releasing the pressure in the heel region and providing support for the arch,thus making the weight of the body distribution more uniform.The finite element model verified in this study can be used to predict foot deformation and contact pressure caused by footwear midsoles,and further provide model support for clinical research of foot diseases.
