Abstract: The present invention relates to a process method for conformal processing of a cylindrical shell inner weld seam by a special mobile robot, a laser scanner is used to scan a cylindrical shell inner weld seam to obtain point cloud data of a contour of a weld seam area first. Weld seam feature identification is carried out to each generatrix, and misidentified generatrices are filtered out to obtain weld seam left and right boundaries. An ideal weld seam processing contour is generated conformally according to the appearance of the weld seam area, weld seam coarse grinding is carried out after correction and compensation, and weld seam contour information after coarse grinding is obtained by scanning after the coarse grinding is completed. Process parameters of the grinding are controlled according to an actual weld seam contour, and weld seam fine grinding is carried out to obtain a smooth weld seam contour.

Abstract: Provided is a method for designing a magnetic gradiometer based on the combined influence of multiple influencing parameters. The method takes into consideration of synergetic interaction of the influencing parameters on the performance of a magnetic gradiometer. It analyzes detection errors within the entire zone of all possible directions and attitudes of a magnetic target under the influence of various influencing parameters, uses the detection accuracy and detection success rate to measure the performance of the magnetic gradiometer accurately and objectively, and finally obtains the influence rule of the influencing parameters on the performance of the magnetic gradiometer. Based on the knowledge of the combined influence of multiple influencing parameters, the magnetic gradiometer can be designed to have high detection accuracy and success rate and high cost-efficiency.
