Abstract: To address the shortcomings of traditional vibration testing methods, a remote vibration parameter testing and dynamic characteristic analysis system was designed using the graphical programming language LabVIEW. Real-time processing, display, and spectrum analysis of acceleration, velocity, and displacement signals of vibrating objects were achieved. The amplitude-frequency characteristic curve of the vibration system was obtained through spline interpolation, and based on this, the estimation of dynamic characteristic parameters such as natural frequency and damping ratio was completed. Simultaneously, network-based remote automatic testing was implemented using Data Socket technology.

Generally, vibration testing involves applying excitation to equipment or structures to cause them to vibrate, and then studying the mechanical dynamic characteristics of the structure through vibration testing. Sometimes, vibration measurement only requires measuring the displacement or velocity, acceleration, and vibration frequency of certain points on the tested object; however, sometimes further analysis and processing of the measured vibration signals are needed, such as spectrum analysis and correlation analysis, to determine the vibration parameters such as the natural frequency and damping ratio of the tested object, and to calculate the frequency response characteristics of the tested object. This necessitates the use of oscilloscopes, spectrum analyzers, and other instruments for recording waveforms. These instruments are often expensive, and only a portion of their functions are used in testing, resulting in low utilization and significant resource waste. This is especially true in large production sites or harsh environments where remote automated testing is often required, where traditional instruments are inadequate. The emergence of virtual instruments effectively solves this problem. Virtual instruments utilize the intelligent functions of computers, such as computing, storage, display, and file management, to software-encode the specialized functions of traditional instruments, creating a completely new instrument system that is identical in appearance and function to traditional hardware instruments while fully utilizing the intelligent resources of a PC. Applying virtual instrument technology to industrial testing can reduce investment in testing equipment. The functions of multiple commonly used instruments, such as oscilloscopes, voltmeters, and spectrum analyzers, can be achieved on a single computer, significantly reducing instrument costs. Furthermore, the software-based architecture of virtual instruments greatly reduces development and maintenance costs. More importantly, virtual instrument testing systems can easily transmit data over a network, allowing for on-site monitoring of the testing process via computer while simultaneously transmitting test data for remote testing.
