Abstract
This dynamic integrated dynamic integrated testing platform on rotary machines not
only can be used as teaching equipments, but also be applicable to scientific research in the
scientific institutions.
The stress and strain, displacement, temperature, speed, torque, vibration and shaft
stiffness of rotating machinery can be tested, primarily using fiber grating, and other sensor
detection technology, combined with the traditional measurement technology. In this paper, to
study for the rotating blades, the platform is developed for the rotating blade shaft stiffness and
stress and strain testing. By testing the leaves under different conditions of stress and strain
distribution, combined with the theoretical analysis, you can sum up all kinds of different
conditions of stress and strain changes in the law, providing the basis for the design of engine
blades and failure analysis.
This paper presents the overall structure of the platform and the principle of experiments.
By calculating and analysis, the mechanical system design is completed, while the test system
made a rough testing method is completed on the basis of system design. I use
three-dimensional modeling software Pro-E to model and simulate, making results more
intuitive. The effect of the testing platform is given, including its photo. Finally, a summary of
the final prospects is finished.
