旋转部件(主旋翼和尾桨)是直升机的主要振动源,对直升机旋转部件动平衡进行精确调整,对提高直升机运行可靠性有重要意义。平衡图是直升机动平衡工作中最重要的工具,对精确调整旋转部件动平衡起着重要的指导作用。本文详细阐述了平衡图的原理、组成、要素、创建过程和使用技巧,对正确、高效使用平衡图具有重要的指导意义。
Rotating parts (main rotor and tail rotor) are the main vibration sources of helicopters. Precise adjustment of the dynamic balance of helicopter rotating parts is of great significance to improve the operational reliability of helicopters. Balance map is the most important tool in helicopter balancing work, which plays an important guiding role in accurately adjusting the balance of rotating components. This paper elaborates the principle, composition, elements, creation process and usage skills of the equilibrium graph, which is of important significance for the correct and efficient use of the equilibrium graph.
