自保障型飞机荷载模拟加载车设计OA

In response to the urgent need for aircraft load simulation in airport pavement research and the issues of existing aircraft load simulation vehicles in terms of operational convenience,load stability,and self-sufficiency,a self-sufficient aircraft simulation loading vehicle design is proposed.Existing vehicles have different design flaws such as no self-propulsion,a high center of gravity,and too many auxiliary wheels.These flaws can result in unstable loading when crossing ruts,a large turning radius,high depen-dence on tractor support,difficulties in relocation and test preparation,and complicated wheel replace-ment.The self-sufficient aircraft simulation loading vehicle designed in this paper is equipped with a single-axle tractor and two spring-loaded auxiliary wheels that share the same axle as the loading wheels.This vehicle also includes triaxial force sensors,a crane,a ladder,and an onboard forklift,which enables the vehicle to load and unload from flatbed trailers and handle counterweights without other mechanical equipment.During operation,its turning radius is less than 10 m.When passing over 150 mm-deep ruts,the loading wheels can bear a load of no less than 150 kN.Moreover,it can collect real-time triaxial load data.With strong self-sufficiency,the vehicle can meet the requirements of loading tests under harsh out-door conditions.
