纵摇角 meaning in Chinese
angle of pitching
pitching angle
Examples
- 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 ) 。 - For the dynamic process of ship rolling movement , this paper analyses its dynamic date with time series analysis method and brings up this system ' s the most excellent autoregressive model ( ar model ) according to least aic criterion ( akaile , information criterion ) . it reveals the regular pattern of ship rolling movement and forecasts the future value of roll angle and pitch angle , then transforms it to adjusting value of object and adjusting it according to appropriate control rules
对于船舶摇荡运动这一动态过程，采用时间序列分析的方法，建立系统的自回归模型( ar模型) ，并根据最小aic信息量判定准则保证建立的系统模型为最优化模型。利用参数模型的方式对船舶横摇、纵摇运动的动态数据进行分析处理，揭示船舶摇荡运动的规律，预测船舶横摇角、纵摇角的未来值。
