| description abstract | This paper investigates buried gas pipelines impacted by an excavator bucket, in addition to the digging load driven by the hydrocylinder of an excavator, and the impact caused by liquid pressure oscillation and the inertial force of the excavator system. These were taken into account for the impact load subjected by the excavator bucket teeth, and the dynamic load coefficient was suggested theoretically. Then the dynamic stress distribution of the buried gas pipeline and corresponding digging limiting load were evaluated by using the strength criterion and the | |
