摘　　要：针对搭载光伏的模块化平台的连接问题,提出一种新型柔性连接件概念模型。根据新型柔性连接件的结构组成,对各个外接弹簧取权,得到附加刚度,实现对连接件各向刚度的精确调整。结合浮式平台动力学、连接件及海域模型进行模拟仿真,调节不同附加刚度,得到1号模块单元的时历响应及连接件主轴的极值载荷。结果表明:高附加刚度可减小连接件主轴的剪切极限载荷,但会增大主轴的拉压极限载荷;当附加刚度为10^(5)N/m时,模块平台的垂荡振幅与无附加刚度相比平均降低67%,大幅降低模块平台单元的垂荡振幅。Aimed at the connection issues of modular platforms equipped with photovoltaics,a new concept model of flexible connector is introduced.Based on the structure of the new flexible connectors,the weight factors are assigned to each external spring.This achieves precise adjustment of the directional stiffness of the connectors through additional stiffness.The simulation integrates the dynamic model of the floating platform,connector model,and marine environment model.The time-history response of the first module unit and the peak load on the main shaft of the connector are obtained by adjusting various additional stiffness.The results indicate that:high additional stiffness can reduce the shear limit load of the main shaft of the connector,but it will increase the tensile and compressive limit loads of the main shaft;when the additional stiffness is 10^(5)N/m,the sway amplitude of the module platform decreases by an average of 67%compared to that without additional stiffness,and the sway amplitude of the module platform units decreases significantly.
