AI Technical Summary

Technical Problem

Existing technologies neglect the coordination of elastic deformation of multiple cables when calculating the internal pressure of a drum under the action of multiple cables, resulting in inaccurate internal pressure calculations and affecting equipment safety and the economic efficiency of structural design.

Method used

By establishing the mechanical equilibrium equation between the drum and the cable, introducing the deformation coordination relationship and Hooke's law, the recursive relationship between the internal pressure of the drum and the winding tension of each layer of cable under multi-layer winding is determined, the internal pressure on the drum when winding to n layers of cable is calculated, and optimization methods and systems are provided.

Benefits of technology

The accuracy of pressure calculation within the drum under multi-layer cable action was achieved. By iteratively calculating and adjusting the drum's geometric parameters, the stress distribution of the structure was optimized, achieving a balance between lightweighting and safety.

Abstract

This invention discloses a recursive calculation method, optimization method, and system for the internal pressure of a drum under cable action, belonging to the field of mechanical design and structural mechanics analysis technology. The method includes the following steps: obtaining the geometric and material parameters of the drum, the geometric and material parameters of the cable, and the winding tension of each layer of cable; establishing a mechanical equilibrium equation between the drum and cable based on the forces acting on them; using the mechanical equilibrium equation, based on deformation compatibility and Hooke's law, determining the recursive relationship between the internal pressure of the drum under multi-layer winding and the winding tension of each layer of cable; and calculating the internal pressure on the drum when winding to n layers of cable based on the recursive relationship. This invention's recursive calculation method for the internal pressure of a drum under cable action, by introducing elastic deformation compatibility conditions in the design of multi-layer cable drums, effectively solves the problem of inaccurate calculation of the internal pressure of the drum shell caused by neglecting the elastic deformation compatibility of multi-layer cables in existing technologies.
