机翼上增挂外挂物后,外挂物对飞机机翼的颤振特性有显著的影响,影响因素之一为外挂物悬挂系统的刚度。本文选择了两种不同机构模拟外挂物悬挂系统刚度,通过刚度和振动测试结果比较了模拟精度,同时从加工和操作两个方面分析了两种机构的优缺点,为以后试验及其它类似试验提供参考及借鉴。
After adding the hang on the wing, the plug on the aircraft wing flutter characteristics have a significant impact, one of the factors that affect the stiffness of the external object suspension system. In this paper, the stiffness of two different kinds of mechanism to simulate the external object suspension system is selected. The simulation accuracy is compared with the test results of stiffness and vibration. At the same time, the advantages and disadvantages of the two mechanisms are analyzed from two aspects of processing and operation, which provide the basis for future experiments and other similar tests Reference and reference.
