Examples
- Study on mixed language programming with fortran and based object languages
与基于对象语言的混合编程研究 - 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。
