Considering that the test system is more complex, it is affected by many objective factors such as the accessories of the test device and the environment, but these factors cannot be considered in the theoretical model, which results in a great difference in the change trend and value between the test data and the theoretical calculation result. Therefore, this paper only compares the spectrum of the test and the theory, and gives the relative test results Percentage of theoretical results.
The corresponding relationship of each frequency in the frequency domain is basically the same, and the error percentage is also small. Therefore, the comparison of experimental and theoretical results shows that the theoretical model established in this paper can effectively analyze the dynamic characteristics of the seal rotor system considering the gear meshing characteristics, and to a certain extent, it can provide theoretical reference for the structural design of the seal.
Experimental study on dynamic characteristics. The experimental study on the dynamic characteristics of the sealed rotor system considering the gear meshing characteristics is carried out under different working conditions. By comparing and analyzing the theoretical results with the experimental results, the rationality of the theoretical model established in this paper is further provided, which verifies that the theoretical model established in this paper can be used for the further study of the dynamic characteristics of the sealed rotor system considering the gear meshing characteristics For theoretical reference, it can also provide theoretical support for the design of sealing structure.
