摘要
讨论了目前国内外在船舶推进轴系扭转振动计算中所应用的诸多方法 ,比较了它们的优缺点。在此基础上 ,提出应用改进的动态矩阵法进行船舶推进轴系的扭振计算 ,并论述了该方法的理论基础 ,使其能更加简单、方便地解决船舶复杂分支推进轴系的扭转振动计算。最后还列举了实际算例的扭振计算 ,证明此方法在解决船舶推进轴系扭振计算方面是一种有效、方便的方法。
Many methods,which can solve torsional vibration of marine propulsion shafting,are discussed in the paper.The advantages and disadvantages of these methods are discussed.Based on the discussion,an improved method is established by modifying the traditional dynamic matrix method which is only fit for shafting without branches.The new method is able to solve torsional vibration of the shafting with branches and has been successfully used in many cases.
