摘　　要：文中设计了一种基于Stewart六自由度并联机构搭建船舶约束模型试验平台.介绍了新型约束模型试验装置的工作原理并推导了试验台驱动腿与物理船模型的运动关系,在此基础上建立了水动力数学模型.对一个矩形框架和两个船模进行了约束模型试验,测量了模型的附加质量系数.将试验结果与理论值进行了比较,验证了该装置的可靠性.A test platform of ship constraint model based on Stewart six-degree-of-freedom parallel mechanism was designed.The working principle of the new constrained model test device was introduced,and the motion relationship between the driving leg of the test bed and the physical ship model was deduced.On this basis,the hydrodynamic mathematical model was established.Constrained model tests of a rectangular frame and two ship models were carried out by using the proposed test device,and the additional mass coefficient of the model was measured.The reliability of the device is verified by comparing the experimental results with the theoretical values.
