纵摇运动 meaning in English
pitching motion
Examples
- The self - tuning fuzzy control algorithm including a back - propagation - based fuzzy controller and the gradient descent method is applied to reduce the pitch motion of the swath ship with control stabilizing fins
控制模式为一自调模糊控制，包括应用一类神经倒传递观念的模糊控制器及梯度下降法来减少纵摇运动。 - The theoretical calculation and the model experimental result both have confirmed that the built - up stabilizing appendage is able to reduce pitching n heaving motions and especially bow acceleration considerably
理论计算和模型试验结果均证明了组合减摇附体能够减小船的纵摇运动、升沉运动，尤其是大幅度降低首部加速度。 - In the end the predicting model is used in watercraft motion modeling and predicting , and the auhor analyzes the result of simulating . the result indicates that this ap $ j $ ifgx9 @ 1 % & itx means is reasonable and feasible and gains the satsfactory pmpose
最后将此模型应用于舰船纵摇运动的极短期预报，并从统计理论的角度对仿真结果进行了分析，分析结果表明该方法是合理可行的，确实提高了预报精度，加长了预报时间。 - On the basis of cybernetics through forecast roll and pitch of a ship and by adjusting the object ' s space position and keep its horizontal state without limit of actual sea state according to the control rules with the predictive value of ship ' s roll angle and pitch angle
应用控制理论通过预测随机海浪扰动下船舶的横摇、纵摇运动的摇角值，按照所设计的控制规律实现在不受实际海况限制的情况下调整船上物体的空间位置，使此物体保持水平状态的目的。 - This paper applies ittc single - parameter ocean wave spectrum to simulate a random long - crested ocean wave according to statistics superposition theory and real - time simulate disturbance on the ship by random wave . it simulates roll and pitch of the ship in random wave in the time domain and gains roll angle ( t ) and pitch angle ( t ) signal of ship rolling movement
本文根据统计叠加理论，采用ittc单参数标准海浪谱仿真模拟实际的长峰波随机海浪，进而实时仿真长峰波随机海浪对船舶的随机扰动，对船舶在海浪中的横摇和纵摇运动进行了时域仿真，得到船舶摇荡运动的横摇角信号( t )和纵摇角信号( t ) 。
