| 摘 要： | 分析了某综合传动装置的外接润滑油管故障的主要原因是由于振动引起的疲劳断裂. 因此，提出了油管的增加支承方案、加隔振结构方案和软管连接方案3种改进方案，并进行了对比验证. 分析及实验测试结果表明，3种改进方案都能有效地抑制振动，提高疲劳强度，改进方案效果优劣依次是增加支承、橡胶隔振、软管连接，幅值分别比改进前衰减了88.29%，77.87%和62.04%.

| Abstract: | Analyzing the fatigue fracture caused by vibration is main fracture reason of the external lubricating oil pipe of a comprehensive transmission device, three improvement schemes of increasing support scheme, adding vibration isolation structure scheme and hose connection scheme were proposed and compared and verified. The analysis and experimental test results show that the three improvement schemes can effectively suppress vibration and improve fatigue strength. The effect of the improved scheme is better in-order to increase the support, rubber vibration isolation and hose connection, and the amplitude is attenuated by 88.29%, 77.87% and 62.04% respectively. |
