为实现对地震作用下大规模土工结构动力学行为的模拟,需要研制较大容量的离心机振动台。文中针对60 g·t水平单向离心机振动台的工作特点和技术要求,提出了吊篮与振动台一体化集成,双缸并推,对称布局的总体设计思路。详细讨论了振动台结构系统中关键结构设计的难点,并给出了可行的结构形式。分析了振动台结构系统在100 g离心场中的应力应变情况,计算了其固有频率。研究结果表明:所设计的结构系统可以满足60 g·t水平单向离心机振动台的技术要求。
In order to simulate the dynamic behavior of large-scale geotechnical structures under the action of earthquake, it is necessary to develop a centrifuge shaking table of larger capacity. In view of the working characteristics and technical requirements of 60 g · t horizontal unidirectional centrifuge shaking table, the overall design idea of integrated integration, double cylinder pushing and symmetrical layout of gondola and shaking table is put forward. The difficulties in the design of the key structure in the vibration table structure system are discussed in detail, and the feasible structure forms are given. The stress and strain of the vibrating table structure system in a centrifugal field of 100 g were analyzed and its natural frequency was calculated. The results show that the designed structural system can meet the technical requirements of 60 g · t horizontal one-way centrifuge shaking table.
