基于参数识别的贮仓--地基系统动力可靠度研究

The silo structure is a important pattern of metallurgy, coal, and grain industry. It is a important need of these industry to research the dynamic reliability of the silo structure. In the research about the dynamic reliability of the silo structure, however, the established computation model and the got parameters have the distance with the infaction because of the simplification and the assumption when building the computation model. Therefore, the established computation model haven't high refinement computing result when researching about the dyramic reliability of the silo structure.The project group has improved the computation model of the dynamic reliability of the silo-foundation system by the parameters identification mathod; identified the parameters of the silo-foundation system with stochastic characteristic, and estimated the dynamic reliability of the silo-foundation system. The project group has studied the all content, arrived at the planning research objective, and obtained the below important results:(1) A series of dynamic experiment has been made on the big pattern vibvation platform.(2) The computation model of researching the dynamic reliability of the silo-foundation system has built.(3) The parameters identification method has advanced which will be used suitable to research the dynamic reliability of the silo-foundation system.(4) The better computation method of the dynamic reliability of the silo-foundation system has established.
