摘要
重点研究在船舶发电机平台这类结构上安置有大型设备的结构振动有限元分析模型的合理性。通过对比研究发电机平台区域的均匀分布质量和大型集中质量其不同有限元模拟方法的优缺点,总结出一套快速、高效、准确的发电机平台振动预报有限元模拟方法。该发电机平台有限元模拟方法能够在详细设计阶段对发电机平台板架的固有频率实现快速准确预报,避免发电机平台板架与主机、螺旋桨等船舶主要激励源发生共振,从而实现发电机平台区域的振动控制。
This article focuses on the rationality of the structural vibration fi nite element analysis model for the ship generator platforms,which is installed with large-scale equipment.A set of rapid,effi cient and accurate fi nite element simulation methods are summarized for the vibration prediction of the generator platform by comparing the advantages and disadvantages of the different fi nite element simulation methods for the uniformly distributed mass and the large concentrated mass of the generator platform region.The fi nite element simulation method of the generator platform can quickly and accurately predict the natural frequency of the generator platform at the detailed design stage to avoid the resonance of the generator platform frame with the main excitation sources of the ship,such as the main engine and the propeller,thereby achieving the vibration control of the generator platform.
