| 本文运用三维弹性接触问题的有限元局部网格密化技术和有限元－线性规划法计算了内啮合直齿轮副在啮合过程中不同接触位置的接触应力分布。对比分析了在系统静载和动载作用下的齿轮接触应力，揭示了内啮合直齿轮在啮合过程中接触应力的变化规律。从而为内啮合直齿轮的接触强度及其可靠性分析奠定基础。 |
| 英文摘要: |
| Contact stress distributions of internal spur gears during the whole engagement periodare evaluated in this paper by using the approach of local mesh refinement of 3-D elastic con-tact problem and finite element-mathematical programming tecnnique.The contact stresses ofthe gears acted by static load are compared with those by dynamic load.Variable tendency ofcontact stresses on internal spur gears during the whole engagement period are revealed.Thisestablishes the basis of contact strength and reliability studies of internal spur gears. |
