Vibration Analysis of Machinery – Diagnostic Spectral Signatures of Common Faults

Vibration analysis is a key technique for diagnosing the technical condition of machines. Different machine faults produce characteristic patterns in the vibration frequency spectrum. By examining the frequency spectrum of machine vibrations (typically via FFT analysis), one can identify specific defect types. Below, common defect categories (imbalance, misalignment, looseness, bearing defects, gear faults) are presented in tables. Each table outlines sub-types of the fault, describing their typical vibration spectrum, the spectral components observed, key identifying features, and an illustrative spectrum graph (embedded as SVG). All frequency references use multiples of the running speed (e.g., “1×” = once-per-revolution frequency). Imbalance Defect Read more…

Linear and Nonlinear Vibrations. Balancing Nonlinear Objects

Linear and Nonlinear Vibrations, Their Features, and Balancing Methods Rotating mechanisms surround us everywhere – from miniature fans in computers to giant turbines at power plants. Their reliable and efficient operation directly depends on balancing – the process of eliminating mass imbalances that lead to unwanted vibrations. Vibrations, in turn, not only reduce the performance and lifespan of equipment but can also cause serious accidents and injuries. Therefore, balancing is a crucial procedure in the production, operation, and maintenance of rotating equipment. Successful balancing requires understanding how an object reacts to the addition or removal of mass. In this context, Read more…

Fan Balancing

Fan Balancing (Information used from ISO 31350-2007 VIBRATION. INDUSTRIAL FANS. REQUIREMENTS FOR PRODUCED VIBRATION AND BALANCING QUALITY) Vibration produced by the fan is one of its most important technical characteristics. It indicates the quality of design and manufacture of the product. Increased vibration may indicate improper installation of the fan, deterioration of its technical condition, etc. For this reason, fan vibration is usually measured during acceptance tests, during installation before commissioning, as well as when performing a machine condition monitoring program. Fan vibration data is also used in the design of its support and connected systems (ducts). Vibration measurements are Read more…

Balancing Instrument at the Price of a Vibrometer

Is it possible? With determination – YES! Balancing instruments rightfully occupy a special place among the wide range of equipment used for vibroacoustic measurements. This is largely due to the fact that this class of instruments, in addition to performing metrological functions, also fulfills a technological role. Essentially, it is technological equipment used to reduce the imbalance of rotary mechanisms. As a result, it offers high economic efficiency, allowing for significant quality improvement of products with relatively small capital investments when implementing balancing equipment. This is especially true for industries where a significant amount of rotary equipment is operated or Read more…
