Research on the Transmission Characteristics of Mechanical Vibration Signals in Optical Axis with Different Diameters

Abstract

In view of the phenomenon that the complex transmission path of signals in the gear box and the lack of analysis and test methods for appropriate vibration source signals, the paper takes different-diameter optical axis as the research object, and firstly establishes the propagation model to analyze how the source signal changes and decays in the optical axis of different diameters from the perspective of wave equation. Then this paper builds proper text platforms to conduct experiment, and verify the correctness and validity of the theory. Besides, through the experiments, the paper analyzes the stress change of the optical axis transverse, the lowing trend of transmission speed of the stress wave in the axis, and the relationship between displacement and scope. At last, the paper aims to verity the rationality and generalization performance of the experimental system, which will support the future study on the transmission characteristics of mechanical vibration signals in optical axis theoretically and experimentally.
