为使船舶Nomoto模型方程形象化，用电阻、电容和放大器搭建电路，经推导其传递函数与船舶Nomoto模型相同，通过适当选取电路元件参数，实现“育鲲轮”的电路机理等效模型。将融入旋回降速补偿后的电路仿真实验结果与实船回转试验结果进行比对，证明电路机理模型可以较高精度等效船舶Nomoto模型，对船舶运动半物理仿真具有重要指导意义。
In order to make the Nomoto model of ships visual, a circuit is built using resistances, capacitors and the amplifiers. The derived transfer function of circuit is the same as the Nomoto model of ships. An equivalent Nomoto model of Vessel Yukun by circuit is realized by appropriately choosing the parameters of circuit elements. The simulation results of circuit added speed loss compensation during turning, indicate that the model of circuit can be equivalent to the Nomoto model with satisfactory precision, comparing with the experimental results of real ship turning. And this has the important guiding significance to the semi-physical simulation of ship motion.
