This invention discloses a decommissioned wind turbine blade dismantling device with self-optimizing shape-finding function, belonging to the field of wind turbine blade dismantling technology. It includes a support frame with support positions for supporting and fixing the airfoil body and a clamping mechanism for clamping the flexible trailing edge. A guide rail is provided on the support frame, and the movement path of the guide rail coincides with the connection between the airfoil body and the flexible trailing edge. A cutting blade capable of moving along the guide rail is installed on the guide rail. The clamping mechanism includes multiple clamping cylinders arranged along the extension direction of the flexible trailing edge, and a drive cylinder fixedly installed on the support frame for pushing the clamping cylinders to move linearly. The support frame has multiple sliding grooves corresponding to the clamping cylinders. A fixing block extending into the sliding groove is fixedly connected to each clamping cylinder, and a spring is fixedly connected between the fixing block and the inner wall of the sliding groove. This invention stretches the flexible trailing edge in the clamping state using the clamping cylinders, putting the flexible trailing edge in a taut state to facilitate cutting.

The invention discloses a spatial self-anchored suspension bridge main cable shape finding calculation method, and belongs to the field of bridge structure design, and the method comprises the following steps: S1, initializing an iteration initial value; s2, respectively carrying out iterative calculation on node relations of the slings and single main cable sections between the slings, and completing iterative calculation of each cable section of the main cable; s3, carrying out deformation compatibility condition judgment on the main cable; s4, if the error precision is not met, calculating the correction amount of the iteration initial value, updating the initial force iteration value, and executing S2; s5, if the error precision is met, other main cable crossing calculation is carried out, and S1 to S4 are repeated; s6, performing finite element calculation; s7, checking whether the error between the coordinate value of the control point of the main beam model and the design value meets the precision requirement or not; if not, correcting the initial strain of the main beam and returning to S6; and if yes, executing S8: taking the counter force at the vertical constraint position of the model obtained in the step S7 as the vertical force borne by the corresponding sling at the anchoring point of the stiffening beam until the main cable line shape at the moment is determined to be the final line shape in the bridge forming state.
