1. HIGH-FREQUENCY VIBRATION TESTING USING PIEZO-
|
||
m+p international has developed a novel method for high-frequency mechanical excitation (> 2 to 40 kHz) of large and heavy specimens in co-operation with Dynamic Mechanics, a specialist for high-frequency exciters. The objective of this method is to excite the specimen or the test fixture using piezoelectric actuators. The technique offers a considerable increase in performance with regard to the achievable frequency limit and vibration amplitude, as well as a reduction in the transverse vibration, at a lower cost than conventional methods.

2. m+p ANALYZER BASICS: OPERATING DEFLECTION
|
|||
In this edition of our m+p Analyzer Basics series, we explain the basics of Operating Deflection Shapes (sometimes called "Operational Deflection Shapes" or ODS). They provide additional insight into vibration problems by visualizing the vibration pattern of a structure. In contrast to modal analysis, which can give similar insight, operating deflection shapes are extracted from measurement data acquired during real-world operation, hence the name "operating" deflection shapes.

3. VIBRATION MEASUREMENTS ON ROTATING MACHINES |
||
With the “Rotate” module, our m+p Analyzer provides many functions required to measure and analyze both fixed and variable speed rotating machines for development diagnostics, commissioning evaluation, post-maintenance performance checks and a host of other monitoring applications. The software package is completed by additional functions such as balancing, bearing condition analysis and other typical performance characteristics of rotating machines. Read more >> |
