| 摘 要： | 针对某载货汽车在市场上发生的打气泵出气钢管断裂问题,对可能导致的原因进行分析并一一排查,最终发现钢管与发动机共振是导致钢管断裂的主要原因。可以通过优化钢管中间固定位置与调整钢管的形状来提高钢管的固有频率,建议通过CAE对打气泵出气钢管进行模态分析,建议其固有频率大于300Hz。 |
| 关 键 词： | 钢管断裂 共振 固有频率 模态分析 |

| Abstract: | A truck in the market place of the pump outlet pipe fracture problems,to analyze the causes and investigation,finally found the steel pipe and the engine resonance tube fracture is the main reason leading to.By optimizing the pipe is fixed in the middle position and adjusting the pipe shape to improve the natural frequency of pipe,as suggested by the CAE rally the air outlet of the air pump pipe modal analysis,the natural frequency is more than 300 Hz. |
| Keywords: | Steel pipe Fracture Resonance Natural Frequency Modal Analysis |
