减摇水舱性能试验摇摆模拟台阻尼力矩的模拟研究

减摇水舱性能试验摇摆模拟台是根据相似准则建立的一种模拟在波浪作用下船舶横摇运动的试验装置。为使摇摆模拟台能够模拟各种类型船舶的运动，要求模拟台的转动惯量、阻尼力矩和波浪干扰力矩都是可调节的。利用硬件方法模拟阻尼力矩具有许多不确定因素，很难保证模拟的阻尼力矩值与要求的阻尼力矩一致，这给减摇水舱性能预报带来诸多困难。本文提出了一种利用软件模拟船舶横摇阻尼力矩的方法，仿真分析和试验结果表明该方法能够模拟各种船舶的阻尼力矩，满足模拟台阻尼力矩模拟要求。

Research on Damping Moment Simulation of Experimental Rolling Simulation Stand for Anti-Rolling Tank Performance

The experimental rolling simulation stand for anti -rolling tank performance is a testing facility of simulating ship rolling move ment in the action of waves based on similarity rules. For simulating the moveme nts of various ship types, it is required that the inertia moment, damping momen t and wave interference moment of simulation stand can be adjusted. Using hardwa re to simulate damping moment has more uncertain factors and is difficult to obt ain the same value of simulated damping moment as required. This will bring a lo t of difficulties to predicting anti-rolling tank performance. This paper provi des a method that can be adopted to simulate ship rolling moment by software. Th e simulation analysis and test results indicate that this method can simulate da mping moments of various ships and satisfy the requirements of simulating dampin g moment for simulation stand.
