Helicopter real vibration environment simulation test system

Abstract

The invention discloses a helicopter real vibration environment simulation test system. The helicopter real vibration environment simulation test system includes a loading platform assembly, a rigidity simulation platform on which a helicopter simulation test member is arranged; three vibration exciter components that are arranged on the loading platform assembly and are connected with the helicopter simulation test member. The three vibration exciter components are cooperated to provide six force factors for the helicopter simulation test member; and the rigidity simulation platform supports the helicopter simulation test member and provides the preset rigidity for the helicopter simulation test member. The helicopter real vibration environment simulation test system can be applied to the in-cabin flight vibration environment simulation of helicopters in all types, provides a flight vibration environment for the helicopter vibration active control system ground test, and designs the guiding direction for the helicopter vibration active control system. The environment characteristic reduction for the typical position in the real helicopter cabin is high in degree.

Description

technical field [0001] The invention relates to the technical field of helicopter vibration active control, in particular to a helicopter real vibration environment simulation test system. Background technique [0002] The ground test of the active vibration control system of the helicopter is mainly the test of the vibration reduction effect of the active vibration control system on the typical position in the helicopter cabin, the robustness test of vibration reduction, the adaptability test and the scientific research test in the development stage. Realizing that the flight vibration environment in a typical position in the helicopter cabin is the same as the real flight vibration environment is the key to the ground test of the active vibration control system of the helicopter. [0003] The ground test of the helicopter active vibration control system is mainly the vibration reduction effect test, the vibration reduction robustness test and the adaptability test of the v...
