Problems solved by technology

Since the environment of the aircraft on the ground is different from that in the air, the vibration response value of the aircraft measured by the hammer tapping method can only be used as a reference, and cannot truly reflect the vibration data of the aircraft during the actual flight.

Abstract

Embodiments of the present invention provide a vibration testing method, device and aircraft, which relate to the technical field of vibration testing. The vibration test method includes: obtaining an adjustment signal; adjusting the control signal of the motor according to the adjustment signal, so that the rotational speed of the motor changes, thereby making the aircraft in a target vibration state; Vibration signals of ; Among them, different structural parts represent structural parts with the same purpose and different composition and structure. The vibration testing method, device and aircraft provided by the invention can measure vibration signals generated by the aircraft during actual flight.

Description

technical field [0001] The invention relates to the technical field of vibration testing, in particular to a vibration testing method, device and aircraft. Background technique [0002] The existing vibration test method is to measure the vibration response value of the aircraft by using the force hammer knocking method. Since the environment of the aircraft on the ground is different from that in the air, the vibration response value of the aircraft measured by the hammer tapping method can only be used as a reference, and cannot truly reflect the vibration data of the aircraft during the actual flight. Contents of the invention [0003] In view of this, the object of the present invention is to provide a vibration testing method, device and aircraft, which can measure the vibration signals generated by the aircraft during actual flight. [0004] In order to achieve the above object, the technical solution adopted in the embodiment of the present invention is as follows:...
