摘要 该文介绍了为配合模拟某型飞机的前轮转弯试验设计的前起落架顶起装置,给出了其总体方案。装置采用气源驱动,顶起执行机构采用三角支撑架体并配有行走轮,保证机构强度和刚度的同时又便于移动,电气控制部分控制电磁换向阀向双作用气缸供气,实现顶起机构的顶起和放下。整个装置结构紧凑、布局合理、维护简单、操作方便、移动灵活,并有故障保护、限位保护和紧急断电保护功能。 The article introduces an aircraft nose landing gear jack-up equipment which is used for simulating an aircraft's nose landing gear swerving test. The main scheme is introduced and the equipment is driven by air. The jack--up actuator is designed as body with three supports and road wheels, this kind of design can not only provide the enough strength and stiffness but also be moved easily. The electrical control section controls the magnetic exchange valve to supply air for the double--acting cylinder, this can achieve the actuator up and down. The equipment is sutably designed with not too much structures and it can be easily maintained, operated and moved, it also has breakdown protection, limit protection and urgency outage protection.
