Abstract:

BACKGROUND: Currently, finite element models are mostly established based on CT imaging to prepare a three dimensional triangular patch model, and then converted into a tetrahedral finite element mesh via commercial software. However, the finite element model has no solid model, and cannot be cut or used as implants.
OBJECTIVE: Based on the anatomical three-dimensional models of China Mechanical Virtual Human Project, an integrated finite element model of entire human musculoskeletal system was built. The weightlifting motor task was implemented and simulated using the proposed finite element model based on the super-computer.
METHODS: Firstly, the three-dimensional models of the musculoskeletal system were reconstructed from the cross-sectional images. Secondly, the segmental finite element model of human musculoskeletal system was built. The finite element model of the entire human musculoskeletal system was constructed through system integrating method. In the end, the motion capture experiment of weightlifting motor task was implemented. The finite element model of the entire human musculoskeletal system weightlifting was simulated and analyzed based on the super-computer Dawning 4000A in Shanghai Super-computer Center.
RESULTS AND CONCLUSION: The integrated method of human musculoskeletal system finite element modeling was developed. An entire human musculoskeletal system finite element model was built. The weightlifting motor task was simulated and the stresses contours of entire musculoskeletal system were obtained. The proposed human musculoskeletal system model could describe the microcosmic mechanical phenomenon of human musculoskeletal system efficaciously and genuinely. It provides a new method for human musculoskeletal biomechanics analysis.
