摘要
箱体作为船舶齿轮传动装置的重要组成部分,在工作过程中由于齿轮系统的激励会产生振动噪声,不仅影响船舱的舒适性,还会对船舶的安全造成威胁。针对船舶齿轮箱尺寸大、结构复杂、安装形式多样的特点,文章从振动噪声的分析方法和控制措施两方面总结了国内外近年来的研究进展。在分析方法方面,对比了采用齿轮系统-箱体全有限元模型进行振动分析与采用齿轮系统集中质量模型和箱体有限元模型进行振动分析的优缺点,评述了有限元法、边界元法、统计能量法、中频混合法等方法的特点及研究进展,总结了计入安装特征影响的方法。在控制措施方面,介绍了以降低振动噪声为目标指导齿轮箱结构改进的方法,总结了确定阻尼材料敷设位置、方式及厚度的方法。最后讨论了需要进一步研究的问题。
As an important part in marine gear transmission system, gearbox will produce vibration and noise in the working process because of the excitation of gear system. This vibration and noise will not only influence the comfort in cabin, but also pose a threat to the security of ship. The research development in analysis method and control measure of marine gearbox vibration and noise is reviewed according to its characteristics such as big size, complex structure, various installation types and so on. In the aspect of analysis method, the advantages and disadvantages of gear system-gearbox finite element model for vibration analysis are compared with those of gear system lumped mass model and gearbox finite element model for vibration analysis. The characteristics and research developments of finite element method (FEM), boundary element method (BEM), statistical energy analysis (SEA), hybrid FE-SEA method, etc. are introduced. The methods to consider the influence of installation types are summarized. In the aspect of control measure, the methods to guide the improvement of gearbox for reduction of vibration and noise are introduced. The methods to determine the damping material arrangement position, way and thickness are summarized. Finally, the problems needed to be further studied are disscussed.
