The B-side support was originally developed in the course of a specific application to reduce the vibration velocities occurring on the DUT. The additional support is particularly helpful with a protruding DUT housing, which is only fixed to the test bed at the front flange.<\/p>\n

In this case, there is a danger that the first natural frequency of the rigid body system will shift down so far that it is within the speed range.<\/p>\n<\/div>\n<\/div>\n

\n
\n

Under certain circumstances, this can lead to shutdown or even damage to the test bed and the DUT.<\/p>\n

On the one hand, the design dampens the vibrations that occur by means of the adjustable damping elements; on the other hand, the additional support stiffens the rigid body system.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
