摘要:

为从实验层面探究静叶调节机构的温度及载荷工况对其阻滞力的影响,考虑运动功能及使用载荷模拟的机构试验设计准则,搭建了原理级的单级调节机构试验系统,提出了采用单向拉压力传感器对机构运行阻滞力进行测试的方法,对不同轴向力负载、环境温度下的拉杆应变以及直动推杆受力情况进行了测试.结果表明,在轴向力载荷与温度单独作用时,阻滞力变化情况与轴向力载荷密切相关,轴向力载荷对阻滞力的影响大于温度对其影响;在载荷与温度共同作用时,轴向力载荷和温度对阻滞力的影响呈现耦合趋势,且在机构回程运动过程中,温度对阻滞力的影响不可忽视.

Abstract:

In order to explore the effect of temperature and load conditions on the retardation force of stator vanes’ regulating mechanism from an experimental level, a single-level regulating mechanism test system is built considering the design criteria of the mechanism experiment based on motion functions and load simulation at the schematic-level. A method for testing the force of the operation mechanism using a unidirectional tension force sensor is proposed. Tests are conducted on the strain of the pull rod under different axial force loads and environmental temperatures, as well as the force on the push rod. The results show that under individual effects of axial force load and temperature, the change in retardation force is closely related to axial force load, and the effect of axial force load on retardation force is larger than that of temperature; when axial force is combined with temperature, the effect of retardation force shows a coupled trend, and the influence of temperature on retardation force cannot be ignored during the mechanism’s return motion.

Key words: stator vanes’ regulating mechanism, retardation force, load condition, experimental system, force test
