The invention provides a high-bearing low-rigidity supporting device for an aircraft vibration test, and belongs to the technical field of jet propulsion devices. Comprising a bearing frame, a movable mechanism and a belleville spring set, the bearing frame comprises an upper end plate, a plurality of guide shafts vertically arranged at the bottom end of the upper end plate, a lower end plate connected with the upper end plate through the guide shafts, and an upper rotating joint arranged at the upper end of the upper end plate; modular design is adopted for all parts of the system, the installation space of the belleville spring sets can be conveniently changed by replacing the upper end plate, the lower end plate, the movable plate and the guide shaft of different sizes, the installation form and number of the belleville spring sets can be adjusted according to actual task requirements, and the rigidity and load requirements of different working conditions are met; compared with a traditional closed cylinder structure, the centering degree of the belleville spring set can be conveniently adjusted, and friction between the belleville spring set and the guide shaft is reduced; the system has the advantages of being simple and compact in structure, convenient to disassemble and assemble and easy to maintain.
本发明提供了一种飞行器振动试验用高承载低刚度支持装置,属于喷气推进装置技术领域。包括承力框架、活动机构以及碟形弹簧组,承力框架包括上端板、垂直设于上端板底端的多个导向轴、通过导向轴与上端板连接的下端板、设于上端板上端的上转动节;该系统各部件采用模块化设计,通过更换不同尺寸上端板和下端板、活动板以及导向轴,可方便改变碟形弹簧组的安装空间,可根据实际任务需要,调整碟形弹簧组的安装形式及数量,满足不同工况的刚度、载重需求;相较于传统的封闭式圆筒结构,方便对碟形弹簧组的对中度进行调校,并减少了碟形弹簧组与导向轴之间的摩擦;该系统具有结构简单紧凑,拆装方便,易于保养维护的优点。
