摘要：
It is necessary and valuable to build the transferring relationship between test bed datum and ship datum for satisfying the boundary requirements of exciting forces in ship's vibration-acoustic analysis. Principle of the force transferring technique for machineries with multiple supporting points is introduced first, and then the measurement method for free velocities of machineries is given. A method for transferring test bed datum to ship datum of machinery force characteristics is discussed and applied to deal with a practical problem, in which the numerical simulation is used for predicting admittance of ship mounting seat absenting reality. Experimental results show that the proposed method is valid.
