Servikal omurga destek sistemi tasarımına yönelik titreşim odaklı çoklu cisimler dinamik modelinin geliştirilmesi

Neck injuries, a common issue with various causes, can range from mild discomfort to severe disability. Despite the abundance of biomechanical models of the cervical spine in the literature, their capabilities for modal and frequency response analysis are limited. A comprehensive head-cervical spine model was developed to address this gap, enabling frequency domain analysis. A multi-body dynamics model with 20 degrees-of-freedom was created using ADAMS software's frequency response analysis capabilities. This model incorporates various elements, including vertebrae, ligaments, and active and passive muscles. Validation was conducted against OpenSim data and existing experimental findings. The model was then employed to conduct a Design of Experiments (DoE) study, where key design factors of a conceptual neck support system were varied. Two vibration objective functions were selected to evaluate the parametric designs from the DoE matrix. The first function identifies the maximum value of the head's frequency response, while the second measures overall vibration within the frequency range of interest. In a case study, the model's capabilities were demonstrated, identifying optimum design parameters for the neck support system. This powerful model, particularly its capacity to calculate vibration-related performance metrics, has the potential to make significant contributions across various industries. Applications range from designing anti-vibration devices to reduce fatigue in the automotive and aerospace sectors to enhancing rehabilitation systems in healthcare, ultimately improving patient exercise effectiveness.
