波面任一点高度
波形高
浪高
Examples
- In the study of directional spectrum and reflection coefficient of multidirectional wave , firstly the wave elevation trains overlapped by the incident wave and the reflected wave of multidirectional wave are simulated in the method of a frequency corresponding to a direction . then the composed wave trains are analyzed respectively by the mbdm and the mmlm . during the numerical study , the input factors include the various wave parameters , the different measuring wave system and the various reflect characteristic
在多向不规则波入射波方向谱和反射系数的分析研究中，利用方向频率对应法模拟了多向不规则波入射波与反射波叠加的波面序列，将此合成波列分别应用mbdm和mmlm进行分析，通过输入各种波浪参量、不同波浪测量系统和各种反射特性等因子，检验了mbdm和mmlm方法的适用条件，对两种分析方法的性能进行了比较分析。 - In general , the upward amplitude curve " curvature is larger , and it changes quicker . on the contrary , the downward is smaller and slower ; because the flare force contains the square of the wave elevation velocity , it results in an difference between the flare force frequence and the associated moving frequence ; the flare force decreases the downward amplitude of heaving oscillations ; the speed of ship has an ignorant effect on the peak values of three calculated values , but there is an obvious effect on the oscillating frequence ; the wave amplitude has an effect on the ship motion , and there is an linear relation between the oscillating amplitude and the wave amplitude on the whole . by the way , there are some experiences and lessons according to the progress calculation : before the calculation of the ship motion , we should checkout the balance in a calm water firstly , namely , the whole displace of ship and the longitudinal position of the center of gravity must be consistent with the draft in calm water , or else , the calculation may show the " floating " phenomenon ; the mixed language programming has a lot of virtues , but it exists a fatal limitation - the debug of dll
研究表明：在某些频率范围内相关水动力系数基本不随吃水变化，只有超过某一频率后水动力系数的值才会出现差异；在横摇方向，水动力系数并没有随着吃水的变化发生规则变化，而是出现了波动现象；近船首剖面的水动力系数计算表明，水动力系数的波动非常大，并远远偏离了平均位置的水动力系数值，值的变化速率也不尽相同，总的看来，上振幅曲线曲率较大，变化较快，下振幅曲线曲率较小，变化较慢；外飘力和波面运动的速度的平方项有关，导致其振动频率和相应运动方向的频率不同；外飘力使升沉向下运动的幅值减小；船速对三个计算量的峰值影响甚微，但对振动频率有明显影响；波幅对船舶运动的影响是明显的，船舶运动的幅值基本上和波幅成线性关系。
