Abstract

An oscillation onset process is analyzed for a test bed intended for carrying out aircraft fatigue tests. A mathematical model is derived to describe a loading for cantilevered aircraft wing with a large aspect ratio value. It is shown that usage of a proportional control law for the loading of elastic inertial system with low damping ration leads to forced oscillations in the system.
