| Abstract: |
| Consider Power Equipment-Vibration Isolators-Thin Plate Foundation was considered as a composite active vibration isolation system in this paper,and the thin plate was clamped.The admittance of the point which transmitted force acted on the foundation would be the intermediate variable;and on the basis of factors analysis about force transmission,admittance,peak displacement of the plate and horizontal distance between peak points,multi-objective optimization of the coupled parameters was carried out.Strength Pareto Evolution Algorithm (SPEA2) was selected as the optimization tool in view of the advantages of less parameter settings,fast convergence,strong optimization capability,and evenly distributed Pareto solution.Peak displacement and the distance between the peak points were considered as the objective functions simultaneously,and the purpose was aimed at controlling the plate vibration effectively while letting let the plate be single peak point vibration as possible,and it would be beneficial for the affiliated equipment and the operators on the plate.Finally,the installation location of isolators was discussed furthermore in accordance with optimal parameters.Numerical results showed that,the method presented could effectively compute the optimal parameters;and it could provide a novel idea for optimal isolation design of industrial buildings and other engineering vibration. |
