摘　　要：为提升浮托安装的效率与成功率,提出一种连续变载模型试验方法,将压载水舱模块化,配合自研的压载调节系统,灵活调节压载分布,能快速连续地调整船舶重量和重心位置分布。同时利用HydroD软件和连续变载模型试验方法,进行波浪作用下的驳船运动响应研究。对比数值计算与试验结果,固有周期最大误差仅为3.3%。自研的压载调节系统可在2%误差内快速实现压载调节,调节效率较高。相较于传统压载调节方法,连续变载模型试验方法可真实模拟动态压载调节过程,实现全过程连续监测,为开展相关有变载需求的船舶模型试验提供参考。To improve the installation efficiency and success rate of the offshore structure by using a float over with time-variant floating state and stress,a model testing method with continuously variable load is proposed,which can flexibly adjust the ballast distribution,weight,and gravity center of the ship.Model tests together with numerical simulation by software HydroD were performed to study the motion response of a barge under the action of waves.Comparing the numerical calculation and experimental results,the maximum error of the natural period is only 3.3%.The self-developed ballast adjustment system can quickly adjust ballast within an error of 2%.Compared with the traditional ballast adjustment method,the continuous variable load method can truly simulate the dynamic ballast adjustment process and achieve continuous full-process monitoring.
