| Abstract: |
| Aiming at solving the problem about improving the vibration effect of horizontal a concrete vibrating table (flat vibrostand),an optimization approach of the vibration table stiffener layout was proposed to optimize the vibration effect.An optimized model was established based on variable density topology optimization method,utilizing the relative density of stiffener elements as design variables and the minimum flexibility of vibration table as the objective.The sensitivity analysis was performed and then the optimized model was analyzed by the optimality criteria method.Finally,according to the topology optimization results,the vibration table stiffeners were rearranged and a reasonable vibrating table structure was obtained.According to the simulation,in the optimized vibration table,the natural frequencies,limit capacity,and flexibility of the structure were improved and a light design was achieved.Additionally,the quality of precast concrete was improved,which provided guidance for flat vibrostand design. |
