Nonlinear dynamical character of ship rolling investigated by harmonic wavelet transform 用谐波小波变换法研究船舶横摇的非线性动力特性
Sea wave high , pitching force , rolling force and rearing torque simulation algorithms are put forward 给出了随机海浪波高、横荡力、横摇力矩、艏摇力矩的仿真算法。
Traditional ship direction keeping and rolling stabilization are referred to be two different problems 传统的船舶航向保持和横摇稳定是分别作为两个独立的问题来处理的。
The platform can analog rolling and swaying motion of ships . the moment of inertia , damping and restoring force can be adjusted 该试验台架能够模拟船舶的横摇运动和横荡运动,试验台架的转动惯量、阻尼力矩和恢复力矩可调。
Finally , we would like to comment on a point made at the end of the roll and ross reply , regarding the presentation of some of our results 最后,我们想要评论在横摇结束的时候被做的一个翎骨针和罗斯答复,关于一些我们的结果的发表。
The influences of potential damping , nonlinear viscous damping , wave heights and wave frequencies in regular beam waves on the safe basin were investigated 分析了非线性横摇方程中势流阻尼、非线性阻尼以及在横向规则波作用下波高和频率对安全池的影响。
As a special technical of ship reducing shake , it almost has one hundred years . in this period , people had made out all kinds of assume to reduce ship shaking 船舶减摇作为一门专门的技术已有近百年的历史,在这期间人们提出了各种设想的装置来减少船舶的横摇。
We have questioned the empirical methodology in the paper by roll and ross , but not the contribution to the literature made by ross , earlier theoretical contribution 我们已经在横摇和罗斯的纸询问经验的方法学,但是不是对被罗斯,较早的理论上的贡献做的文学的贡献。
The test results indicated that test rolling table can simulate ship rolling motions on the wave and passive u - tube tank designed achieves stabilization effects to a certain extent 试验摇摆台的成功研制,将为装备减摇水舱的实船进行准确且可靠的横摇运动预报提供一个稳定的试验平台。
