摘　　要：基于大型有限元分析软件MSC.Patran & Nastran,建立了某艇用减速器箱体结构分析的三维有限元分析模型,采用保圆假设,实现了箱体孔和轴接触及传力的简化分析。比照本文结果与西北工业大学的同期计算结果,两者一致性很好,说明了本文结果是正确的,模型是合理的。Based on the large FEM software MSC. Pat-ran ＆ Nastran, a 3-D FEM structure analysis model of the body structure of one shipborne reducer gear-box is established. A simplified analysis of the contact and load-transmitting between box bore and axes is carried out by the hypothesis of circle-holding. Compared the number result of the paper with that of the NWPU, a very good agreement is gotten. It shows that the results of the paper are exact and model is rational.
