There are natural frequencies in all equipment that have components. Generally, they exist in the 8 to 200 Hz environmental spectrum. Figure 46.1 demonstrates the transmissibility and resonant ...

Vibration testing and analysis. This has been referred to in a number of different ways, most of which are not meant to be complimentary. Voodoo box, black magic, rocket scientist stuff, etc. It is an ...

It took decades for technology to catch up with the math that a researcher worked out to control vibration table shakers. This researcher knew that shaking in all directions at once was the key to ...

The OVTT(TM), OmniAxial (TM) Vibration Table Top, series introduced the first stand-alone, compact, repetitive-shock vibration system on the market and features Qualmark's patented six degree of ...

Whole-body vibration (WBV) is a common occupational risk for workers using heavy construction machinery such as bulldozers, tractors, and forklifts as well as transportation drivers of buses, trains, ...

Shock and vibration testing systems have been developed in order to understand the ability of electronic equipment to respond to the effects of environmental stresses. These testing systems are force ...

Vibration testing helps to predict how well a product will withstand its intended service or transportation environment. Some new vibration controllers have the capability to replicate data recorded ...

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 ...

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 ...
