Three-way Alliance provides one-stop for
Modal Test solutions.

The alliance of three noise and vibration measurement
specialists, Brüel & Kjaer, Endevco and Ometron has
resulted in an organisation that covers every aspect of
modal testing, creating a "one-stop" shop for modal test
solutions.

Aiming to become the preferred choice for all modal requirements,
the alliance draws on its members' vast reserves of experience
built up over decades. Modal test solutions on offer encompass
everything from impact hammers, transducers and non-contact
vibrometers to data acquisition/analysis platforms and modal
analysis software.

No matter what a modal test application requires, customers can
select from the widest possible range of transducer technologies
including piezoelectric (PE), DeltaTron, ISOTRON, piezoresistive
(PR) or variable capacitance (VC). The range also includes smart
transducers compatible with IEEE P1451.5 Transducers Electronic
Data Sheet (TEDS) and the alliance can also provide mounting,
positioning and orientation accessories.

Non-contact vibration transducer technologies such as single-point
and scanning Laser Doppler Vibrometers (LDV5) can also be
provided for applications where it is impossible or undesirable
to mount an array of accelerometers on a vibrating object.

Modal excitation can be provided through either a range of impact
hammers or modal exciters.

A new and complete line of Endevco impact hammers with
integrated DeltaTron/ISOTRON outputs is available for experimental
modal analysis of anything from small disk drives to large civil
engineering structures. This is complemented by a range of robust
modal exciters designed to handle even the most demanding
modal test applications. Features include force ratings (sine)
from 100 to 1000N, low weight armatures, up to 2" stroke capability,
special "hole through" armature for tension wire stinger technology
and rare earth magnet technology on some types.

Data acquisition and analysis solutions on offer include PULSE,
a versatile, task oriented multi-analysis system that allows
measurement and analysis of from 2 to 32 channels. The software
in PULSE can basically be used for any type of noise and vibration
analysis including mobility measurements. Adding the dedicated
Modal Test Consultant1M software turns PULSE into a very
powerful structural dynamics measurement platform focusing on
the very time consuming data acquisition aspects of preparing,
performing and validating such measurements.

PULSE is complemented by Intelligent Data Acquisition (IDA) a
fully featured front-end specifically developed for large-scale
multichannel sound and vibration data acquisition.

A wide range of signal conditioning products is also available
including the Optimal Architecture Sensor Interface System (OASIS)
low cost, high density signal conditioning system that provides an
interface for multiple transducer types. New DeltaTron conditioning
units for multichannel applications can also be supplied.

Complementing the wide range of hardware for modal test
applications, Bruel & Kjaer also supplies powerful software solutions
to help simplify setting up and reduce the time taken to perform
structural dynamic measurements. Modal Test Consultant is one
such solution and this is accompanied by modal parameter
extraction software (ME'scopeVES) and Operational Modal
Analysis software.

Bruel & Kjaer's one-stop shop Modal Test Solutions are described
in a new brochure just published by the company. The 16-page
brochure provides a comprehensive introduction to modal testing
with a description of the modal testing measurement chain and how
the Bruel & Kjaer, Ometron and Endevco alliance covers every aspect.
Additional sections cover transducer technologies, modal excitation,
data acquisition and analysis, multichannel signal conditioning
and software. Examples of modal test solutions are also provided
to illustrate the versatility of the various products available.

Available free-of-charge, Bruel & Kjaer's new Modal Test Solutions
brochure is available from the company on 01438 739000 or email
info@bkgb.co.uk. For serious modal users, the company also offers
a multimedia presentation of Modal Testing and Analysis covering
PULSE Multi-analyser and Modal Test Consultant. Contact Bruel &
Kjaer on +44(0) 1438 739000 to arrange for a sales engineer to call
with a copy.
