Abstract

The application provides a kind of umbilical cable cross section layout multi-objective optimization design method based on quasi-physical algorithm, establishes the multi-objective optimization design model with cross section compactness, balance, heat source dispersity as optimization target and component non-overlapping as constraint condition. First, the complex mathematical optimization formula of umbilical cable cross section layout optimization is simplified into a physical model by using the idea of quasi-physical method, then a pattern is randomly generated as the initial layout to make a series of movements under the action of various physical forces, and the total potential energy at the end of calculation is calculated, then the next iteration or new layout is generated according to the total potential energy, and finally the optimal cross section layout form is obtained. The application realizes the optimization design of umbilical cable cross section layout containing multiple components by using quasi-physical algorithm, and the method can replace manual operation and provide a useful reference for umbilical cable cross section layout design.
