摘要

当前针对周转轮系均载问题的研究，侧重分析单个激励变化下的均载行为，缺乏调查内外激励共同变化时的均载机理，以致在众多影响轮系均载的激励因素中，难以找出决定均载行为的关键激励，从而高效提升轮系均载性能。为研究这一问题，提出并建立了均载性能的多因素分析模型，将复合行星轮系“平移-扭转”动力学模型与正交试验法相结合，计算不同激励配置下的动态均载系数；采用信噪比和方差分析法，量化和比较各激励对均载系数的影响权值，找出并优化决定均载的关键激励。计算结果表明，内部激励对均载性能的影响远大于外部激励，适当增加轴承间隙可以提升均载性能，减小中心构件的传递误差能最为高效地提升均载性能。

Abstract

Current researches on load sharing characteristic concentrate on fluctuation of load sharing under the condition of single factor changing， which results in a poor comprehension on the load sharing behavior under the condition of multi-factors changing together，that’s to say， it’s difficult to find the most essential excitation among multi-factors affecting load sharing behavior，to improve the load sharing characteristic efficiently. To solve this problem，a multiple-factor analysis model is built and incorporated with “translational-rotaional” dynamic model of compound planetary gear set to give load sharing coefficient under different confugurations. By using single to noise analysis， and the contribution of each control parameter on load sharing behavior is quantified. The results indicate that， the impact of internal excitations on load sharing behavior is much bigger than that of external excitations， increasing bearing clearance contributes to load sharing behavior， and decreasing the transmission error of central parts is the most efficient way to improve load sharing behavior.
