摘　　要：针对水下训练服随遇平衡和特定角度下稳定平衡的浮力配平需求,通过对配平过程进行数学描述,基于分支定界算法的整数非线性规划,提出了一种用于浮力配平方案优化计算的方法.对给定初始值的水下训练服,在随遇平衡和不同角度下的稳定平衡条件下,计算得到最优的浮力配平结果,表明了该方法计算配平方案的有效性.该方法对不同配平对象、配平目标的浮力配平过程都有很好的指导意义.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.
