Abstract

The multi-support rotary shafting system, represented by the ship propulsion shafting, is widely used in the power transmission device of the ship, and its working condition has a great influence on the operational safety of the ship. Therefore, it is necessary to conduct a dynamic analysis of the ship propulsion shafting. The ship propulsion shafting is used as a prototype to design a transmission shaft system fault detection platform based on the dual-engine parallel transmission mode. In order to accurately simulate the load loaded by the magnetic powder brake in the fault detection platform of the transmission shaft system, the control strategy of the magnetic powder brake loading is studied, including conventional PID control, Smith control, fuzzy Smith control and fuzzy Smith with integral action. The control realizes the ideal control effect of the magnetic powder brake. On the basis of the accurate load control effect, use the Adams software to conduct dynamic simulation analysis on the rigid-flexible hybrid model of the ship propulsion shafting. The dynamic characteristics of the shaft system under normal and fault conditions are studied, the research shows that the occurrence of collision and friction faults will increase the force fluctuation range of the shaft system, the shafting vibration will become more complex, and the characteristic frequency will have a large number of high-multiplication frequencies. The above analysis results have certain significance for the fault analysis of the transmission shaft system.

多支承转轴系统动力学仿真分析

以船舶推进轴系为代表的多支承旋转轴系广泛应用于船舶的动力传动装置中，其工作状态对船舶的运行安全有很大影响。因此，有必要对船舶推进轴系进行动力学分析。以船舶推进轴系为原型，设计了基于双机并联传动方式的传动轴系故障检测平台。为了准确模拟磁粉制动器在传动轴系统故障检测平台中所加载的负载，研究了磁粉制动器负载的控制策略，包括常规PID控制、Smith控制、模糊Smith控制和积分作用模糊Smith控制。实现了磁粉制动器的理想控制效果。在获得准确载荷控制效果的基础上，利用Adams软件对船舶推进轴系刚柔混合模型进行了动态仿真分析。对正常工况和故障工况下轴系的动态特性进行了研究，研究表明，碰撞和摩擦故障的发生会增大轴系的力波动范围，轴系振动会变得更加复杂，特征频率会有大量的高倍频。上述分析结果对传动轴系统的故障分析具有一定的意义。
