摘　　要：直升机自动倾斜器大轴承是旋翼操纵系统中的重要承力组件,其载荷特性的研究对直升机自动倾斜器设计有重要意义。文章依据对直升机主旋翼变距拉杆飞行实测载荷数据的分析,建立了变距拉杆载荷公式的简化模型,并以此为基础,分别推导出了双叶旋翼、三叶旋翼以及多叶旋翼构型的自动倾斜器大轴承弯矩载荷特性函数,提供了一种可用于直升机自动倾斜器大轴承工程设计的载荷计算方法。Swashplate ball bearing of helicopter is an important load bearing component in rotor control system, the analysis of its load Characteristics is of great significance to helicopter design.In this paper, a simplified load model of pitch link is established, which based on the data analysis of flight test, according to this load model, the moment functions of swashplate ball bearing with two blades rotor, three blades rotor or more are established respectively. This paper provides a load calculation method which can be used in the engineering design of helicopter swashplate ball bearing.
