This paper focuses on FEM simulation model of pneumatic spring implemented into cushioning of a car seat. This spring is a part of a device which ensures controlled change pressure distribution in contact zone between car seat and passenger. This spring made up from silicone and foam parts and from the tape. In this article, the material properties of these materials are experimentally investigated in order to get parameters for their mathematical models implemented in FEM software MSC.Marc. The simulation of the spring is then carried out with changing internal pressure. Keywords: silicone rubber, polyurethane foam, pneumatic spring, finite element analysis, material fitting data, MSC.Marc. 1. Introduction The seat with the implemented pneumatic spring contains an active vibration-isolation element in accordance with the patented solution [1]. The spring is made up from parts produces from different materials – foam, silicone and the material of tape. Mechanical properties of these materials are investigated experimentally to fit mathematical simulation models.
