工程船舶作业力矩作用下的横摇运动

Rolling Motion of Engineering Ships under the Operating Moment

应用时域分析法求得了工程船舶在作业力矩作用下的横摇脉冲响应函数，应用１２艘工程船模型横摇水动力系数试验值，计算了横摇响应的运动历程，为此类船舶的横摇角计算和设计提供了依据．

An analyzing method in time domain is applied to obtain the rolling pulse response functions of engineering ships under the operating moment. The motion course of rolling responseis calculated by use of experimental results on hydrodynawic force coeffieients of 12 engineering ship models,which provide the basis of rolling angle calculation and design for engineering ships.
