Abstrakt v dalším jazyce:	In computer graphics and in industrial context, Mass-Spring model is used to obtain fast and visual results in physical simulations. A disadvantage of the method is to obtain accurate result on account of the difficulty to define parameters of a Mass-Spring Model. Different works and results are carried out to define Mass-Spring parameters in other domains such as in cloth animation or in soft tissue modeling. However the Mass-Spring model is not used in some context where a real-time computation can be useful as in tire manufacturing industry for example. In this paper, a method is presented to define the geometric configuration of a Mass-Spring system and the tuning of the mass, stiffness and damper parameters according to physical material behaviours. Different load cases are studied and used to conduct a sensitivity study on the network spring parameters. Then, results are compared to Finite Element Model of same cases in order to evaluate the precision of the proposed approach.
