| Zusammenfassung: | The invention belongs to the technical field of gas cylinder testing, and discloses a novel gas cylinder volume residual deformation rate measuring method, which comprises the following steps: S1, scanning the contour of a gas cylinder by using a three-dimensional laser scanner in three stages, namely before pressurizing, after pressure maintaining and after pressure relief of the gas cylinder, and collecting three-dimensional point cloud data of the contour of the gas cylinder; s2, based on the three-dimensional point cloud data, utilizing engineering software to reversely reconstruct a gas cylinder geometric model; s3, calculating the volume V1 of the gas cylinder before pressurizing, the volume V2 of the gas cylinder after pressure maintaining and the volume V3 of the gas cylinder after pressure relief according to the gas cylinder geometric model; and S4, calculating by using a gas cylinder volume residual deformation rate formula to obtain a measurement result. The method can solve the problems that a tr |
