This invention provides a shot peening strengthening process for improving the surface hardness of precision long shaft parts, belonging to the field of precision machining technology. The invention involves pre-treating the surface of the precision long shaft part, establishing a discrete mesh model of the long shaft and collecting initial residual stress distribution data, activating an online dynamic load compensation support system to control the axial runout within a threshold range, and driving the spray gun to perform continuous shot peening along a spiral trajectory based on the process timing parameters output by the physical information-constrained spatiotemporal jump graph attention model. The invention also utilizes a multi-channel acoustic emission signal sequence to output real-time predicted values ​​of the residual stress field, inputting these predicted values ​​into a shot peening strengthening process game-theoretic control model to drive a follow-up reverse hydraulic straightening device to actively suppress bending deformation and perform supplementary shot peening on areas that do not meet the standards. This solves the technical problem of difficulty in real-time suppression of bending deformation caused by uneven residual stress field distribution during the shot peening strengthening process of precision long shaft parts.

The application belongs to the technical field of steel wire rope detection, and specifically discloses a marine steel wire rope detection device, which comprises a needle bearing and a rotating drum rotatably arranged in the needle bearing, further comprises a variable-pitch adjusting mechanism symmetrically arranged in the rotating drum, a radial synchronous adapting mechanism symmetrically arranged outside the rotating drum, and an external gear ring threadedly arranged at the front end of the rotating drum, each variable-pitch adjusting mechanism comprises a plurality of universal bull's eye wheels arranged along the axial direction of the rotating drum, and a distance measuring sensor for detecting the relative position change between the adjacent universal bull's eye wheels is arranged between the adjacent universal bull's eye wheels. The radial synchronous adapting mechanism is used for pressing the bull's eye wheels into the grooves between the strands of the steel wire rope, and through the axial relative movement between the device and the steel wire rope, each bull's eye wheel is limited by the support of the needle bearing and rotates adaptively along the spiral track of the groove between the strands, and any uneven change of the gap between the strands will be directly converted into the measurable relative displacement of the bull's eye wheel in the axial position, so that the automatic detection of the lay length parameter is realized.
