The invention relates to a rocker arm type undercarriage force transmission loading fake part, and belongs to the technical field of airplane structure strength static force/fatigue tests. A rocker arm type undercarriage fake part is consistent with a real undercarriage in key force transmission point coordinate and constraint mode, the structural strength of the rocker arm type undercarriage fake part meets the full-cycle requirement of a full-aircraft fatigue test, and the rocker arm type undercarriage fake part comprises a main supporting column fake part, a lower rocker arm fake part, an upper supporting arm fake part, a main rotating shaft fake part and the like, and further comprises a fake wheel and a fixing support. The false wheel comprises a wheel shaft and a loading plate, one end of the wheel shaft is a polygonal wheel shaft anti-rotation matching section used for transmitting the X-direction load of a landing point of the undercarriage, the wheel shaft anti-rotation matching section is matched with a mounting hole formed in the lower rocker arm false part and is in inserted connection with the mounting hole, the loading plate is arranged at the other end of the wheel shaft, and a plurality of loading holes are formed in the loading plate; the fixing support is installed at the tail end of the lower rocker arm fake piece. The method has the following advantages: the full cycle of the full-machine fatigue test is met; the cost can be saved; the functional requirements of the rocker arm type undercarriage are met; the fixing support supports the airplane in a static state.

    本发明涉及一种摇臂式起落架传力加载假件,属于飞机结构强度静力/疲劳试验技术领域。一种摇臂式起落架假件,其关键传力点坐标、约束方式与真实起落架一致,结构强度满足全机疲劳试验全周期要求,包括主支柱假件、下摇臂假件、上支臂假件、主转轴假件……,还包括假轮和固定支架;假轮包括轮轴、加载板,轮轴的一端为多边形轮轴防转配合段,用于传递起落架的触地点X向载荷,轮轴防转配合段与开设在下摇臂假件上的安装孔适配,且与安装孔插接,加载板设置在轮轴的另一端,其上开设有若干加载孔;固定支架安装在下摇臂假件的末端。本发明具有如下优点:满足全机疲劳试验全周期;可节约成本;实现摇臂式起落架的功能需求;固定支架静态时支撑飞机。
