Force Rating Basis During Vibration Test on ED Shakers

Force = Mass x Acceleration This equation is the basis for selecting sizing shakers and determining if your shaker can perform a specific shock or vibration test. The premise is this: the more mass you put on your shaker, the less acceleration the shaker can produce. And vice-versa: the less mass you put on your …

Which Vibration System Will Meet Your Needs? Repetitive Shock or Electro-Dynamic

The classic ElectroDynamic (ED) vibration system has been used for many years to accelerate vibration fatigue in Accelerated Life Testing (ALT). Shaped random Power Spectral Density excitation (PSDs) were specified to meet specific stress goals, and they could be generated and controlled very precisely. The profile, shown in Figure 1, became a de facto standard …
