Abstract:
Objective To create a model with simple expression of mechanical characteristics of the human chest for the development of a manikin. Methods A simplified Gruben-model was proposed based on the anatomical structure and physical characteristics of the materials, and perfect coefficients were computed. The model feasibility was proved by the coefficient of determination and residual analysis.Results The mathematic form of the model provided had three fewer terms than Gruben′s. The coefficient of determination approximated 1, the residue was small, and the perfect coefficients of "a typical human" were determined.Conclusion The hypothesis of the model makes the coefficients physically meaningful, which provides a new method to study the force-displacement relationship of the thorax. Also the simple form makes it easy to create the model and provide some guidance for the design of a manikin′s chest.
