USES Lateral Modal Exciter Stands UA 1607 and UA 1608 are
used for demanding modal test applications and are
matched for use with Modal Exciter Types 4824, 4825
and 4826
FEATURES Durable and extremely rugged construction Two different heights 1.4 meters and 2.0 meters Perfectly suited for use with push/pull stingers as well
as tension wire stingers Exciter can be suspended via four turnbuckles (standard
accessory), or positioned on top of bracket arm Modal Exciter Types 4824, 4825 and 4826 have the
possibility of 360 degrees of rotation when mounted on
top of bracket arm Heavy-duty wheels for easy movability Aluminium Iprofile arm for easy custombuilt exciter
suspension Low-geared spindle for swift change of exciter height Rubber feet on adjustable steel legs Pre-tensioning of tension wire stingers via turnbuckle
and coil spring (standard accessory)
Description
Designed for demanding modal test applications, Lateral
Modal Exciter Stands UA 1607 and UA 1608 provide reliable,
stable and long-lived operation. A rugged construction and
a variety of possibilities for modal exciter mounting, assure
a versatile means of lateral modal excitation for any modal
test requiring attached excitation.
The Lateral Modal Exciter Stands UA 1607 and UA 1608 are
designed to be used in conjunction with Brüel & Kjær Mo-
dal Exciter Types 4824, 4825 and 4826, but they can be
used with any exciter (with or without added inertial mass)
up to a maximum suspended weight of 60 kg. Mounting of
the modal exciter can be achieved via the classical sus-
pension method using four turnbuckles or via a unique
mounting plate that allows the modal exciter to be mount-
ed on top of the bracket arm. The latter provides for the
possibility of rotating the exciter 360 degrees around its
own main axis, making excitation setup from under a struc-
ture as easy as lateral excitation from the side of the struc-
ture.
Lateral Modal Exciter Stands UA 1607 and UA 1608 are suit-
ed for push/pull stingers as well as tension wire stingers,
such as Brüel & Kjærs UA 1600. In a traditional setup for
horizontal excitation, the latter is accommodated by feed-
ing the tension wire through the modal exciter, mounted
in its trunnion and suspended via four turnbuckles. The
tension wire then goes around the pulley (height adjusta-
ble) and finally connects to a turnbuckle fastened to the
base of the Lateral Modal Exciter Stand (UA 1607 or
UA 1608), via a coil spring. The coil spring has a pre-ten-
sioning limit of 400 N (90 lbf).
An (optional) DC Static Centering Unit Type 1056, allows
the use of tension wire stingers, even when the modal
exciter is mounted on top of the bracket arm. The DC Static
Centering Unit makes it possible to achieve wire pre-ten-
sioning by adding an adjustable DC current to the AC cur-
rent (drive signal) from the power amplifier, hence
providing the necessary pre-tensioning of the attached
wire.
