摘　　要：利用齿轮箱系统分析软件MASTA和大型通用CAE软件MSC Patran&Nastran,建立船用齿轮箱啮合分析模型和箱体有限元模型,分析对比多工况下齿轮箱箱体载荷,并进行结构效能分析评价。基于应力场平衡原理,结合强度和刚度的约束,以减少冗余材料为目标,设计箱体的轻量化结构,通过对轻量化箱体的模态分析,避免了齿轮箱系统的共振。目前,应用此方法进行箱体轻量化的大功率船用齿轮箱已经量产,轻量化后的齿轮箱箱体重量降低了19%,达到轻量化的目的。Using the gearbox system analysis software MASTA and the large-scale general CAE software MSC Patran&Nastran,the meshing analysis model and the box finite element model of the marine gearbox are established.The load of the gearbox under multiple loading cases is analyzed and compared,and the structural efficiency are analyzed and evaluated.Based on the principle of stress field balance and the constraint of strength and stiffness,the lightweight structure of the box is designed to reduce redundant materials.Through the modal analysis of the lightweight box,the resonance of the gearbox system is avoided.At present,the high power marine gearbox with this method has been mass-produced,and the weight of the gearbox box has been reduced by 19%after lightweight,so as to achieve the purpose of lightweight.
