Abstract

Abstract

Aimed at neutral balancing and specific-angle stable balancing of the underwater training spacesuit, through the mathematical description of the buoyancy balancing process, a new method of optimizing calculation for the buoyancy balancing scheme was proposed based on integer nonlinear programming of the branch and bound algorithm. According to given initial values of the underwater training spacesuit and under conditions of neutral balancing and different-angle stable balancing, the optimal buoyancy balancing results were calculated. The results demonstrate the effectiveness and efficiency of the method in calculation of the balancing scheme. This method makes a good guidance for the buoyancy balancing process of different balancing objects and balancing tasks.
