| 摘 要： | 用光弹性应力分析,论证了美国卡特皮勒拖拉机公司的齿轮类线接触疲劳试样具有可靠的线接触模拟性;证明了用静应力场分析动载下接触疲劳裂纹形成与扩展的可靠性;并运用应力分布状况分析了裂纹可能的形成位置和扩展方向;揭示了应力状态与各种点蚀形貌及形成之间的关系,从而证明点蚀的形成及形貌是由表层应力状态决定的。

| Abstract: | Photoelastic stress analysis proves reliable line contact simulation of samples for gear style contact fatigue parts designed by Caterpillar Tractor Co., USA. Static stress field can be reliably applied to analyse initiation and extension of contact fatigue cracks under motive load. Stress distribution is used to analyse possible initiating origin and propagation directions of cracks.It is revealed that formation and morphology of etch-pits are dominated by stress condition of surface layer. |
