The vibration test yielded the following conclusions.

Lightweight Carbon Composite Chassis for Engine Start Lithium Batteries

Team, today part of the Noise and Vibration Technologies Group, was working on a different type of orthogonal 6DOF concept before March, 2005, the date of the company's patent US 6,860,152, "High Frequency Multiple Degree of Freedom Vibration Test Machine." The configuration described in the patent used only six actuators but opposed the horizontal shakers with fixed preload pistons.

On Tuesday, NASA announced that it had since carried out three low-level vibration tests of the telescope - currently housed in a clean room at the Goddard Space Flight Center in Greenbelt, Maryland - and was now close to determining the cause of the anomaly.

Development of MDOF specific reference criteria and the inclusion of the MDOF criteria in military specifications are essential to the accuracy of an MDOF vibration test. As expected, this element of the MDOF vibration test lags behind the development of the laboratory test technology, but likely will see increased near-term activity.

Dynamic testing: toward a multiple exciter test

In line with all-Union State Standard it is available to replace random probability vibration test by equivalent sine wave vibration.
