    Analysis of the Load Sharing Characteristic of Compound Planetary Gear Set Under the Common Impact of Internal and External Excitation by Chao Yang, Haibo Zhang, Huijuan Zhu, Liping Feng

    Published 2019-06-01
    “…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. …”
