飞机起落架撑杆锁弹簧是下位锁机构实现功能的关键部件,其设计过程需要考虑其与下位锁开锁作动筒的协调以及其对收放载荷和起落架自由放性能的影响。讨论了撑杆锁弹簧的设计流程以及弹簧设计过程中需要考虑的因素,介绍了一种区别于传统受力分析确定弹簧工作拉力的方法,并例举了一种支承式撑杆锁弹簧的设计与计算过程。
Aircraft landing gear stay bar spring is a key component of the lower locking mechanism. Its design process needs to consider its coordination with the lower locking and unlocking cylinder and its impact on the retractable load and the free-fall performance of the landing gear. The design flow of the strut lock spring and the factors to be considered in the spring design process are discussed. A method to determine the working tension of the spring is introduced, which is different from the traditional stress analysis. The design of a strut spring And the calculation process.
