Read MoreVibration testing is continuously evolving throughout time. The requirements of testing large and heavy devices demand shakers with larger sizes and higher force ratings. On the other hand, with the increase of size and force ratings comes the cost of lowering the usable frequency range of a shaker system. Shakers with 50,000 lbf force typically operates up to 2 kHz. Larger shakers can have usable frequency ranges of less than 1.5 kHz. The main reason for this frequency reduction in performance is that higher force requires larger armature, and this results in a lower first resonance frequency, thus reducing the useful shaker frequency range. Intuitively, the larger the shaker, the higher the price tag.
Read MoreNoise Criteria (NC) curves are primarily used to rate indoor noise levels. It is important that the background noise levels are within acceptable limits to ensure optimal speech communication for structures ranging from residences and offices to hospitals and schools.
Read MoreThe Stability Diagram is an effective way to display and identify the modes of a structure under test. Nowadays, the Stability Diagram is the standard method for the modal parameter identification stage. It provides a graphical representation of the system's poles (modes) at different mode orders during the modal parameter identification stage.

Read MoreSummertime…birds chirp in the warm early mornings, crickets sing late into the evening haze, and the Vibration Institute holds their Annual Training Conference and Expo! This year’s exhibition was hosted by VI as well as Reliabilityweb.com, the world’s most trusted source of the latest reliability and uptime maintenance news and information in the Predictive Maintenance and Reliability Industries. As organizers of the expo, they even hosted numerous interesting live-streamed interviews with industry professionals right on the exhibit floor.
Read MoreStability is an important part of ensuring operability of power generation systems. Large transients can cause power systems to become unstable and can eventually lead to blackouts. Power systems need to be designed to withstand large disturbances and maintain stability under changing operating conditions. Devices such as the generator automatic voltage regulator (AVR) and power system stabilizer (PSS) are widely used to manage these system instabilities. These control devices can be attached to power generation systems to help improve stability.
Read MoreThe EDM Modal MIMO Stepped Sine Testing option provides multiple Stepped Sine excitations to measure Frequency Response Functions (FRFs). The MIMO Stepped Sine test runs with one frequency at a time, thus providing a high signal-to-noise ratio of sine excitations. The drive voltages can be specified, or input forces are controlled to provide the proper excitation levels for the structure under test. During MIMO Stepped Sine testing, a multiple number of sweeps with different phase conditions are implemented to make the MIMO FRF measurement possible. This process is equivalent to the randomized phase situation of MIMO FRF testing using uncorrelated random excitation methods. An accurate sine tracking filter provides leakage-free response spectra. A system identification step prior to the stepped sine test helps control excitation levels.
