LING Electronics Vibration – Shaker (contact for quote)

In 2009, Data Physics acquired Ling Electronics from Qualmark. The legendary Ling Electronics products have become the Data Physics “LE” product range – continuing a legacy of quality and performance in environmental vibration testing that you can trust.

With LING’s exclusive Lin-E-Air Isolation System, the shaker body is suspended onair springs located at the trunnions. The Li n-E-Ai r system i nco rpora tes Ii nearbearings which guide body motion in thethrust axis, simplifying alignment withauxiliary horizontal tables. A low naturalfrequency of the body suspension provides excellent isolation and eliminates theneed for expensive isolated reactionmasses in most applications. Base leveling screws are provided

F=ma, or Force = Mass x Acceleration

Force: is the required force of the shaker for the given acceleration and mass. Vibration systems have different force ratings for Random, Sine, and Shock.

Mass: is the total moving mass including the shaker’s armature. The DUT, fixture, head expander (if applicable) or slip table + drive bar + bearings, and the shaker’s armature all add into the mass.

Acceleration: is given by the profiles to be tested, typically units of g for Sine and Shock, and g rms for Random.

If we think of force as directly proportional to an amplifier’s current output rating, then in general terms, the bigger and heavier the test item, the more power you’ll need to conduct your testing. Additionally, the higher the required test acceleration (g or g rms), the more power you’ll need. In sizing the proper replacement amplifier, it is important to know the system’s operational characteristics to match the best suited solution. Just as force is directly proportional to current, the shaker’s velocity is directly proportional to voltage. The maximum power of the shaker system is usually found right at the velocity to acceleration cross-over point.
