Description

Technical Field

[0001] This invention relates to the field of marine engineering and new energy equipment technology, and in particular to a dynamic submarine cable clamp design method, system and equipment for progressively upgrading and iterating. Background Technology

[0002] Dynamic submarine cables are key power transmission and communication equipment connecting floating equipment in offshore engineering to submarine power and signal systems. Unlike static submarine cables fixed to the seabed, dynamic submarine cables operate in a dynamic marine environment with waves, ocean currents, and floating body movements (heave, sway, drift), which places extremely high demands on the mechanical properties, fatigue life, and cable protection capabilities of the fixing clamps.

[0003] As a core component of dynamic cables in marine engineering, the design quality of dynamic submarine cable clamps directly affects the reliability and safety of the entire marine equipment.

[0004] Currently, traditional fixture design generally relies on the designer's engineering experience and lacks systematic theoretical guidance. Some designers have attempted to introduce numerical simulation methods, but most adopt a "one-step iteration" approach with a single model, that is, repeatedly calculating and correcting on the final three-dimensional geometric model.

[0005] The above method has the following significant drawbacks in practical applications: 1. Lack of systematic theoretical and numerical methods: Traditional design processes mainly rely on empirical analogies or simple static estimations, without effectively introducing mature theories such as contact mechanics (e.g., Hertz contact theory) and nonlinear mechanics analysis. This results in a lack of positive calculation basis for the design of key parameters such as clamping force, radius of curvature, and anti-bending device interface of the fixture, which poses a risk of design redundancy or insufficient protection.

[0006] 2. One-step iterative mode leads to cross-influence of process parameters and low design efficiency: Existing one-step iterative methods often directly simulate and modify the final complex 3D fixture model. Parameters at multiple levels, such as the overall stiffness distribution of the fixture, local contact stress, and installation details, are coupled and cross-influenced within the same model, leading to repeated trial and error. Each iteration requires a large amount of computational and pre- and post-processing resources, resulting in a long design cycle and low efficiency. Summary of the Invention

[0007] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dynamic submarine cable clamp design method, system and equipment for progressively upgrading and iterating.

[0008] In the first aspect, to solve the above-mentioned technical problems, the present invention provides a dynamic submarine cable clamp design method of progressively increasing dimensionality and iterative design, including sequentially executing one-dimensional parameter design, two-dimensional parameter design and three-dimensional parameter design; The one-dimensional parameter design includes: inputting the required tensile strength, friction coefficient of the padding material, and dynamic submarine cable main body parameters; calculating the required one-dimensional macroscopic parameters of the clamp based on one-dimensional theoretical equations, wherein the one-dimensional macroscopic parameters include total clamping force, clamping force per unit length, average pressure of the padding, maximum contact pressure of the padding, and padding thickness; outputting the overall dimensions of the clamping padding and the clamping force of the clamping body; performing one-dimensional theoretical verification; if the verification does not meet the one-dimensional convergence condition, backtracking and adjusting the input parameters to re-perform the one-dimensional parameter design; if the verification meets the one-dimensional convergence condition, proceeding to two-dimensional parameter design. The two-dimensional parameter design includes: based on the above one-dimensional macroscopic parameters, extracting the cross-sections of the clamping section and the transition interface of the anti-bend device to establish a two-dimensional contact model, introducing Hertzian contact theory, inputting material parameters, dynamic submarine cable tolerances and expansion coefficients into the two-dimensional contact model, and outputting two-dimensional contact design parameters and two-dimensional macroscopic parameters. The two-dimensional contact design parameters include the contact pressure distribution, contact half-width and maximum contact stress between the clamp and the outer sheath of the submarine cable. The two-dimensional macroscopic parameters include the inner and outer diameters of the clamp, the depth of the assembly groove and the size of the liner. Two-dimensional numerical verification is performed based on the two-dimensional macroscopic parameters. If the verification does not meet the two-dimensional convergence conditions, the two-dimensional input parameters are backtracked and the two-dimensional parameter design is carried out again. If the verification meets the two-dimensional convergence conditions, the three-dimensional parameter design is entered. The three-dimensional parameter design includes: based on the above one-dimensional macroscopic parameters, two-dimensional contact design parameters and two-dimensional macroscopic parameters, constructing a three-dimensional fixture geometric model, applying combined marine environmental loads, performing nonlinear finite element analysis, and outputting the fixture outer contour dimensions and fastener dimensions. If the verification does not meet the three-dimensional convergence conditions, the input parameters are backtracked and the three-dimensional parameter design is carried out again. If the verification meets the three-dimensional convergence conditions, the design is completed.

[0009] In one embodiment of the present invention, the specific method for calculating the one-dimensional macroscopic parameters required for the fixture based on one-dimensional theoretical equations is as follows: The specific method for calculating the one-dimensional macroscopic parameters required for the fixture based on one-dimensional theoretical equations is as follows: Based on the design requirements for tensile strength F and the friction coefficient μ of the liner material. t Calculate the total clamping force required by the fixture: F t1 =F / μ t ; According to the total clamping force F t1 Calculate the clamping force per unit length based on the effective axial length L1 of the coastal cable: f t1 =F t1 / L1 According to the clamping force per unit length f t1 Calculate the average pressure of the liner based on the liner width W1 and the number of liner n: C1 = f t1 / (nW1) Based on Hertzian contact theory, combined with the clamping force f per unit length t1 The maximum contact pressure of the liner is calculated using the structural elastic modulus Et and the cable curvature ρt.

[0010] Based on the gap B between the inner cavity of the clamp and the submarine cable t The padding thickness is calculated based on the elastic modulus E1 of the padding material and the average padding pressure C1: B1 = B t E1 / C1.

[0011] In one embodiment of the present invention, the one-dimensional convergence conditions include: the maximum contact pressure of the pad is not greater than the allowable contact stress of the submarine cable material; the pad thickness B1 should be less than the pad width and greater than the gap between the clamp cavity and the submarine cable; and the fastener specifications corresponding to the clamping force can be selected from the standard parts library.

[0012] In one embodiment of the present invention, the two-dimensional convergence condition is: the contact pressure between the clamp and the outer sheath of the submarine cable is lower than the yield value and the allowable crushing value of the submarine cable material and is uniformly distributed.

[0013] In one embodiment of the present invention, the three-dimensional convergence conditions include: the fixture profile, bolt assembly position, local strength of the fixture body, and bolt strength meet the set requirements.

[0014] In one embodiment of the present invention, the three-dimensional convergence condition further includes that the dimensions of the sacrificial anode of the fixture meet the corrosion protection requirements.

[0015] In one embodiment of the present invention, the combined marine environmental load includes wave load, current load, floating body motion acceleration load, and temperature load.

[0016] Secondly, in order to solve the above-mentioned technical problems, the present invention provides a dynamic submarine cable clamp design system, comprising: The one-dimensional design module is used to obtain the one-dimensional macroscopic parameters required for the design, such as tensile force, friction coefficient of the padding material, and dynamic submarine cable main body parameters. Based on the one-dimensional theoretical equation, it calculates the total clamping force, unit length clamping force, average pressure of the padding, maximum contact pressure of the padding, and padding thickness required by the fixture, and outputs the overall dimensions of the fixture padding and the clamping force of the fixture main body. The two-dimensional design module is used to extract the cross-section of the clamping section and the transition interface of the anti-bend device based on the one-dimensional macroscopic parameters, establish a two-dimensional contact model, and use Hertz contact theory to input material parameters, dynamic submarine cable tolerances and expansion coefficients into the model. It outputs the contact pressure distribution, contact half-width and maximum contact stress between the clamp and the outer sheath of the submarine cable, and outputs the inner and outer diameters of the clamp, the depth of the assembly groove and the detailed dimensions of the pad. The 3D design module is used to construct a 3D fixture geometric model based on the above-mentioned one-dimensional macroscopic parameters, two-dimensional contact design parameters, and two-dimensional macroscopic parameters, apply combined marine environmental loads, perform nonlinear finite element analysis, verify and fine-tune local details, and output the fixture outer contour dimensions and fastener dimensions.

[0017] In one embodiment of the present invention, an iteration control module is also included, which is used to control the reverse positioning to backtrack to the current module and re-iterate when the iteration of each module fails, and to control the entry into the next module after the iteration of each module converges, until the design is completed after the iteration of the three-dimensional design module converges.

[0018] Thirdly, in order to solve the above-mentioned technical problems, the present invention provides an electronic device, including a processor and a memory, wherein the memory stores a computer program, and the computer program, when executed by the processor, implements the method described in the first aspect.

[0019] Compared with the prior art, the above-described technical solution of the present invention has the following advantages: (1) A dynamic submarine cable clamp layer design is adopted, which involves progressively upgrading the dimensions of one-dimensional, two-dimensional, and three-dimensional clamps. In the one-dimensional stage, theoretical equations are used to quickly determine the macroscopic clamping parameters and achieve preliminary scheme selection. In the two-dimensional stage, Hertzian contact theory is introduced to quantitatively calculate the contact characteristics of each sheath layer of the submarine cable, solve the contact problem during clamp execution, and avoid the risk of sheath extrusion damage. In the three-dimensional stage, the preceding parameters are integrated to construct a complete model and finite element verification is carried out under marine environmental loads. The gradual improvement from one-dimensional main body to three-dimensional details reduces parameter cross-iteration, and each dimension can be iterated independently and quickly, reducing the calculation cost by more than an order of magnitude. At the same time, the design convergence process is more stable and controllable, and the design efficiency is accelerated.

[0020] (2) By implementing one-dimensional, two-dimensional, and three-dimensional hierarchical progressive control, reasonable constraints, uniform contact stress, and stress-free details are ensured, making fixture design quantifiable and easy to program for automated iteration, further reducing reliance on experience and improving the theoretical rigor and reliability of the design. Furthermore, when each level of verification fails, iterative optimization is performed only within the current level, without the need for a complete recalculation, effectively reducing the workload of numerical simulation and improving design efficiency.
