摘　　要：提出一种基于有限元理论的复杂浮筏系统功率流的计算方法.该方法可应用ANSYS等有限元软件直观得生成复杂浮筏系统的模型,并采用谐响应分析技术求解线性系统在外激励下的响应,从而求得计算系统功率流所需的力和速度向量.应用该方法研究了一实际复杂浮筏系统的功率流传递特性,算例结果表明了方法的可靠性.A method was proposed for investigating the characteristic of the vibratory power transmission of the complex floating raft system by the finite element method （FEM）. This method allows straightforward generation of a structural model of a complex floating raft system in FEM software ANSYS. By means of the harmonic response analysis technique, the response of the linear system under multiple harmonic excitations can be determined. Thus the desired vectors required to calculate the power transmission can be obtained. Based on this method, the vibratory power transmission of a practical complex floating raft system was investigated numerically. This work shows the validity of the proposed method.
