Abstract: Spindle rotation error directly correlates with the quality of mechanical processing. Currently, the error was mainly converted through measuring the distance information of standard component installed at the tool position, ...

Abstract: The pipeline inspection gauges (PIGs) are often blocked in actual operation. As the PIG ran in the straight pipeline, elbow, and anomaly, the large deformation and stress state of the power section cup were analyzed by a ...

Abstract: The precise prediction of the driving force has significant meaning in preventing blockage accidents in oil and gas pipeline pigging engineering. In this paper, a novel prediction model is established for the typical ...
