Blade is an important part of rotating machinery, and the vibration of blade is one of the main causes of blade failure. Its safety and reliability become an important indicator of whether rotating machinery can work normally. Through the research and analysis of vibration data, we can effectively understand the operation status of the equipment. At the same time, using computer to do all kinds of data analysis is not only convenient and reliable, it provides convenience for engineering application, but also becomes the main means to deal with all kinds of information. It is very important to test and analyze the key equipment. Based on the vibration test data of blower blades, a vibration signal analysis system of rotating machinery is developed by using the powerful function of VB development software and Microsoft Office Access database. Its main work and results are: 1. By studying the fast Fourier transform (FFT) and the time-based FFT algorithm, a FFT algorithm based on the mixed radix-2 / 3 basis is designed. This analysis method can save the memory unit effectively. Improve computational efficiency. 2. A data analysis system based on the vibration data of blower blade is developed in VB environment. Its main function is to carry on the fast Fourier transform to the test data, analyze the spectrum characteristic, design the humanized visual interface. 3. Combined with Microsoft Office Access database, the database management system is designed. The system can call database data, receive test data in real time, transform test data, and manage test data. Through the testing of the system function and the personal experience of the users, the system can satisfy the effective analysis of the vibration test data, the simple and intuitive data interface makes the user operation very easy, and the database design is more convenient for the analysis effect of the data. At the same time, the appropriate algorithm improves the speed of software running and makes the software performance better.
