| Insert-column hydraulic support is a new supporting equipment that applied in the fully mechanized coal mining face. It replaced four connecting rod mechanism, which is applied in traditional hydraulic support, with insert column. Insert-column hydraulic support possesses the advantages of simple structure, strong shock resistance, short design cycle and convenient maintenance, etc.According to the design requirements and the structure characteristics of insert-column hydraulic support, the overall design and parts design are completed, the main parameters are confirmed. Based on the performance and structure parameters, the three-dimensional model of this insert-column support is set up with the help of Pro/E.Under load working condition, the static mechanics analysis is conducted by ANSYS Workbench. The results show that the insert-column support can meet the requirements of strength and rigidity. According to the analysis results, the position of the maximum stress of insert-column support is obtained, and the component structure of support is improved reasonably.In order to improve the economy of the hydraulic support, study on the overall weight reduce of this support is conducted under the condition of satisfying the strength and rigidity. Structural optimization is a better method to reduce the weight of the engineering structure. In this paper, the topology optimization and size optimization are applied in the structure optimization design of the insert-column support.According to the theory of topology optimization, the topology optimization of canopy is analyzed based on Opti Struct module in Hyperworks software. The number and layout of the transverse bar plates in the canopy can be get from the results of optimization. Based on topology optimization, the model of insert-column support is updated. Then Design Explorer module in ANSYS Workbench Software is used to the multi-condition optimization by size optimization theory. The best size scheme of canopy and the base can be gotten from the results of optimization.In this thesis, the insert-column hydraulic support is designed, and finite element analysis, topolopy optimization and size optimization analysis are carried out, which is a reference for the study of insert-column hydraulic support in the future. |
