Abstract

The invention discloses an optimal design method for a high-pressure rubber hose structure on the basis of a finite element. The method comprises the following steps that: S1: utilizing ANSYS to establish a parameterized finite element model; S2: setting the value range of a design and state variable, and determining an optimal design target function; S3: selecting an iterative algorithm to carryout iterative calculation; S4: according to an optimal design result, correcting each processing technological parameter to enable the technological parameter to own better practical operability; andS5: performing an experiment to verify the rationality of an optimal design scheme. By use of the optimal design method for the high-pressure rubber hose structure on the basis of the finite element,a parameterized and theoretical design method can be provided for high-pressure rubber hoses of different models and working pressures, so that the rubber hose of each model can be subjected to mass design and production, the blindness of a traditional experience design method can be lowered, the pressure bearing evenness of the rubber hose is improved, a design period is shortened, design cost islowered, and design efficiency is improved.

Description

technical field [0001] The invention relates to a method for optimizing the structure of a high-pressure rubber hose, in particular to a method for optimizing the structure of a high-pressure rubber hose based on finite elements, and belongs to the technical field of high-pressure rubber hose production. Background technique [0002] High-pressure hoses are widely used in offshore oil drilling, choke and kill, and heave compensation devices. Its structure is mainly composed of inner rubber layer, reinforced layer (steel wire / rubber composite layer) and outer rubber layer. It has the characteristics of corrosion resistance and high temperature resistance, but there are also problems of heavy weight, high cost and uneven pressure bearing. [0003] There are still many deficiencies and defects in the existing design method of high-pressure steel wire wound rubber hose. Before the design, there is a lack of systematic analysis and theoretical calculation of the structure of each...
