Abstract:
The application of a novel laser vibration tester in vibration monitoring experimental teaching is discussed. Firstly, the main characteristics and use occasions of the instrument are analyzed. Secondly, the experimental bench and experimental steps are designed. Thirdly, the different parameters under the condition of the test results are compared. Then, the time domain curve and the frequency domain characteristic curve of the vibrating body are obtained. Finally, the factors affecting the test results and the precautions are discussed, which lays a foundation for the application of laser vibration tester in engineering practice.
