摘　　要：水下航行器舵系统振动特性的快速、准确计算是进行舵系统水弹性和振动控制研究的关键。为了研究舵系统关键部件的结构参数对其振动特性的影响,本文基于多体系统传递矩阵法建立了舵系统动力学高效仿真模型,并与商业软件ANSYS的仿真结果进行对比分析,验证模型的准确性。计算结果表明:基于多体系统传递矩阵法的舵系统振动特性计算效率远高于ANSYS软件。舵系统的第1、3阶为对称模型,第2、4阶为反对称模态且为局部模态。增加液压弹簧刚度可以增加舵系统第1、3阶的频率,相当于增加了操纵系统的等效扭转刚度,可以抑制舵叶俯仰运动。Efficient and accurate simulation of the vibration characteristics of the hydroplane system of an underwater vehicle is the key to the study of the hydroelasticity and vibration control of the hydroplane system. To analyze the influence of the structural parameters of the hydroplane system′s key components on its vibration characteristics, an efficient dynamic simulation model of the hydroplane system established on the basis of the ransfer matrix method for multibody systems(MSTMM). The simulation results of the proposed model compared with those of the commercial software ANSYS, and the accuracy of the model verified. The simulation results show that the calculation efficiency of the hydroplane system′s vibration characteristics based on the MSTMM is higher than that of commercial software ANSYS. The first and third orders of the hydroplane system are symmetric modes. Meanwhile, the second and fourth orders are antisymmetric and local modes. Increasing the stiffness of the hydraulic spring can increase the frequency of the first and third orders of the hydroplane system, which is equivalent to the increase in the equivalent torsional stiffness of the steering system, and restrain the pitching motion of the hydroplanes.
