摘要: 针对脉冲展开式飞网的展开稳定性问题,从网面质量分布角度开展研究。首先基于传递矩阵方法、集中质量法和反比例函数推导建立了较优的网面质量分布模型。然后结合遗传算法优化得到了网面最优的质量分布状态,并通过大量数值仿真和回归分析得到了网面质量分布经验公式。提出的网面质量分布模型有效降低了网面质量分布问题中的优化变量个数,提升了网面质量分布最优解的求解效率。网面质量分布最优解所对应的网面展开稳定性得到大幅提升,网面质量分布经验公式对应的网面展开状态与最优解对应的网面展开状态基本一致。结果表明,将网面质量分布模型和网面质量分布经验公式应用到脉冲展开式飞网将有效提升飞网的展开稳定性。

Abstract: Aiming at the problem of deployment stability of the single pulse deployed space net, the research is carried out from the perspective of the mass distribution on the net. Firstly, a better mass distribution model is established based on the transfer matrix method, lumped mass method and inverse proportion function. Then, the optimal mass distribution of the net is obtained by a genetic algorithm, and the empirical formula of the mass distribution is obtained by a large number of numerical simulation and regression analysis. The proposed mass distribution model effectively reduces the number of optimization variables in the net surface mass distribution and improves the efficiency of solving the optimal solution. The deployment stability of the optimized net corresponding to the optimal solution is greatly improved, which is basically consistent with the result of the empirical formula. Results show that the application of the mass distribution model and the empirical formula can effectively improve the deployment stability of the single pulse deployed space net.
