| 摘 要： | 综合考虑齿轮啮合力及箱体重力作用,采用有限元法建立大功率船用齿轮箱的有限元静力学模型,分析计算4种工况下齿轮箱的承载能力,并对原齿轮箱的强度和结构刚度进行分析评价.基于等强度原则,将优化设计与可靠性设计理论相结合,建立齿轮箱优化模型.在满足齿轮箱结构安全的条件下,对齿轮箱进行优化设计.优化后的齿轮箱重量减轻1.06 t,并且强度分布趋向均匀,结构变得更加合理,具有一定的理论和工程实用价值.

| Abstract: | Taking the influences of joggle forces and gravity into account,a static model of a high-power marine gearbox was established using the finite element method.The gearbox workload capacity was calculated in four working states.Gearbox strength and structural rigidity were analyzed.Combining theories of optimization and reliability design,the gearbox optimization model was obtained based on the intensity principle.To insure a safe structure,optimization designs were put in practice to improve the gearbox stru... |
