Aircraft structures are prone to vibrations due to their lightweight construction. In most cases, these vibrations are not critical. They decay due to damping effects from aerodynamic forces and ...

The National Electrical Manufacturers Association (NEMA), Rosslyn, VA, has a new standard out for street and area lighting that addresses the impact of vibration on roadway lighting. NEMA published ...

Airbus is planning to use a quicker technique to validate ground-vibration responses on the A330neo, having tested it on the A350-1000. The airframer says the testing is designed to assess the ...

The HVAC Systems Sound and Vibration Procedural Guide details methods and processes that, when followed, provide repeatable measurement and verification of sound and vibration (S&V) levels, as ...

The ability to measure, monitor, and analyze vibration is essential to many industries and areas of research & development. Unfortunately, the proper methods for creating an accurate and repeatable ...

Jet engine vibration is arguably the worst enemy of a typical aircraft maintenance team. Parts which are out of balance can eventually result in a cracked turbine, fan, and compressor components, as ...

It’s easy to take for granted equipment that runs smoothly and is comfortable to operate. However, a great deal of research and testing goes into optimizing the vibration of an engine. Advancements in ...

Vibration testing emerged in the early 1960s as electronics systems became more complex and widely available. This led to a need for greater reliability, with one of the major early adopters being the ...
