861 - Finite element and optimisation model for passive techniques in vibration attenuation of mechanical components
Matos Neves M.
Abstract
A computational model is being developed to investigate the potential of combining finite element analysis (FEA) and topology optimisation in passive attenuation of vibrations at mechanical components. With this continuous regions of attenuation were obtained in the transmissibility curves through FEA and optimisation. The model was tested in cantilever beam driven by vibratory forces. A generalization of the problem for more general 3D solid mechanical components using the potential from topology optimization concept and sensitivity analysis is presented. Results obtained show transmissibility peaks vanishing or being bounded. (? SS16 )
