Plenary lecture 11: non-linear approaches on dynamics of multibody mechanical systems with advanced computing tools

The study deal with non-linear approaches in dynamic behaviour analysis for multibody mechanical systems by using advanced computing and simulation tools. The main application of this work consist by dynamics estimation of some construction equipments during their technological processes, with strong various and intensive dynamic working states. The proposed methodology is capable to simulate the non-linear characteristics of interaction between machine and terrain, and involve some innovative modelling and computing tools. The analysis are based on derived MIMO technique, and provide a strong method to treat a large set both of the inputs - as an external disturbances, and of the outputs - as undesirable equipment movements. Non-linear and multibody approaches, through their realistic modelling specific methods, leads to a high efficacy on dynamic behaviour evaluation, with direct impact in optimization of design and exploitation of technological equipments.
