A Review Study of Vibration Analysis for a Seated Human and Presenting an Optimal Biomechanical Model for a Vehicle Passenger by Genetic Algorithm

In the present study, different biomechanical models in a sitting position have been investigated. The differences of these models are in terms of the number degrees of freedom, the complexity and the direction of the vibration analysis that consist the vertical, horizontal and lateral directions. In addition, mathematical models indurin finite element, lumped-parameter, multi-body and matrix models that are presented in literature, are reviewed. These models have been compared with the experimental data in terms of compliance and the best model is specified. In addition, the history of important laboratory works in from 2000 to 2015, which are vital for validation are collected and presented. In fact, compliance biomechanical models with experimental results, shows the good biomechanical model. Finally, 6-DoF biomechanical model of human body for a sitting posture without backrest is introduced, which is utilized for investigating vibrations in vertical direction. Model parameters using genetic algorithms is obtained by minimizing the errors. This model is validated with the experimental results which presented by Boileau et al.The results demonstrated that the presented model has better compliance with the experimental data in compare with the previous models.
