由于海洋环境复杂多变以及串并混联构型海上稳定廊桥动力学特性的复杂，海上稳定廊桥工作过程的动力学特性分析一直是相关研究过程中的重点和难点。针对这一问题，首先，基于矢量法和凯恩方法得出海上稳定廊桥各部件投影矩阵与Jacobi矩阵以及在广义坐标系下的动力学方程，运用凯恩方法和虚功原理得出海上稳定廊桥整体显式动力学模型；其次，基于Simulink搭建MATLAB与Adams联合仿真模型，并以MSS工具箱对船舶的模拟运动为激励进行分析。最后，在有、无人员货物转运两种工况下，进行理论计算与仿真分析，验证所建立模型的正确性。进一步，研究不同质量的负载对支链驱动力的影响，以及对海上稳定廊桥的补偿效果进行分析。研究成果对海上稳定廊桥的研制和实船应用具有一定指导意义。

Due to the complexity and variability of the marine environment as well as the complexity of the dynamic characteristics of the offshore stabilized corridor bridge in a series-parallel hybrid configuration, the analysis of the dynamic characteristics of the offshore stabilized corridor bridge in the working process has always been a key point and a difficult point in the related research process. To address this problem, firstly, the projection matrix and Jacobi matrix of each component of the bridge were derived based on the vector method and Kane's method, as well as the dynamic equations under the generalized coordinate system, and the overall explicit dynamics model of the bridge was derived by using the Kane's method and the principle of virtual work. Secondly, a joint simulation model of MATLAB and Adams was constructed based on Simulink and the simulated motion of the vessel was simulated by the MSS toolbox to simulate the ship's motion as an excitation for analysis. Finally, theoretical calculations and simulation analysis were carried out under two working conditions, with and without personnel and cargo transfer, to verify the correctness of the established model. Further, the effects of loads of different masses on the driving force of the strut chain were investigated, and the compensating effect of the sea-stabilised corridor bridge was analysed. The research results are of guiding significance for the development of the sea-stabilised corridor bridge and its application on real ships.
