Sammanfattning (abstract):
In this paper two computational models for commercial vehicle engine vibration dynamics are presented. The first model is conventional elastomeric engine mounting system comprising elastic, viscous and friction functional components which expresses the nonlinear behaviour of the dynamic stiffness and damping of the engine mounts as functions of both the frequency and amplitude of excitation. The second model is based on adding actuators, sensors and a controller to the elastomeric mounts making the engine mounting system an adaptronic one. Parameter optimization of the proposed adaptronic engine mounting system has been done. Computational models are implemented in Matlab /Simulink with GUI suitable for engine vibration dynamics analysis under different engine excitations and realistic road inputs. Simulations of engine vibration and transmitted forces to the vehicle structure are presented which are obtained by using both computational models for the same inputs of engine and road excitations. Comparison of the obtained results for adaptronic mounting system (AMS) to the corresponding results of conventional mounting system (CMS) demonstrates up to %24 reduction in the magnitude of the transmitted force to the vehicle structure achieved with adaptronic engine mounting system that includes two actuators with forces not exceeding 50 (N).
