Contact and non-contact methods of vibration measurement in aircraft structures

Measurement of vibrations of the entire aircraft or individual components is very important in the design and operation of aircraft. It should be known that the correct performance of such measurements requires specialized measuring devices, appropriate knowledge and experience. This paper presents two basic methods of measuring the vibration of realaircraft structures. The presented measuring apparatus are dedicated to the aviation industry. First, the apparatus for measuring vibrations with the contact method will be presented, and then with the non-contact method. The advantages and disadvantages of both methods will be presented and examples of application will be shown.
