dc.description.abstract- Derivation of the analytical model of the pneumatic spring system with lumped parameters + Analysis of the system using a multidisciplinary approach. + Numerical simulation of the model for different working conditions (constant stiffness and constant pressure mode, quasi-static load, dynamic load). + Investigation of the dynamical behavior of the system. Numerical simulation of transmission of acceleration.- Finding a solution to improve the system from the point of view of faster regulation of pressure inside the PSE Providing a theoretical basis for the idea of improvement and solution. Carrying out the numerical simulation of the improved system.- Investigation the influence of the PSE on transmission of acceleration. + Comparison of simulation results between original and improved systems. + Comparison of experimental results between original and improved systems. + Assessment of quality of the system improvement.- Creation of FEM model of the seat with adjustable pressure profile in interaction with a simplified model of the human body + Determination of suitable constitutive models for materials of seat's parts. + Modelling of interaction between a foam block with a PSE inserted and a mass to simulate the deformation of PSE and foam under static conditions. + Modelling of interaction between the car seat cushion with a PSE inserted and a simplified human body. + Calculation of the pressure profile in the contact zone between the seat and simplified human body. Comparison with the experimental results.cs
