Original Abstract

Linear structural components joined by means of elastomer parts play an important role in automotive industry. Elastomeric mountings of engines and rubber torsional vibration dampers of crankshafts are typical representatives of such components. Some computational problems, however, can arise when finite element modelling or a multibody software is used to investigate systems with structural components. The approximation by means of multi-parameter mass-spring-damper models is frequently utilized to overcome this issue. The paper presents computational results obtained with the use of the generalized modified Kelvin model. The optimization model was used to approximate experimentally acquired data of the dynamic stiffness of a rubber silentblock for automotive use. The model was implemented in GAMS software, which allows for non-linear optimization. Simulation results show that the fourth-order generalized modified Kelvin model enables a great approximation of the considered rubber silentblock.
