MTS and National Instruments Join to Reduce Noise and Vibration Test Time

Product Integration Adds Measurements to Design Phase of Automotive and
Aerospace NVH Applications

TRAVERSE CITY, Michigan, May 6, 2003. Design engineers now can streamline
noise, vibration and harshness (NVH) evaluations by integrating MTS Systems
Corporation (Nasdaq: MTSC) I-DEAS Pro and Sound Engineering families of
noise and vibration analysis software with National Instruments (Nasdaq:
NATI) LabVIEW graphical development software and family of dynamic signal
acquisition hardware. The hardware integration and measurement capabilities
of the LabVIEW platform combined with the design tool integration and
analysis capabilities of MTS products helps engineers easily incorporate
measurements into the design phase of automotive and aerospace NVH
applications to more easily validate designs.

"The integration between NI products and MTS NVH software and processes
gives our customers access to a broad range of measurement capabilities for
applications ranging from large scale aircraft ground vibration test to
automotive acoustic imaging," said Doug Marinaro, MTS vice president of
software and consulting. "This enhanced capability adds to our extensive
offering of practical noise and vibration engineering solutions, which
enable our customers to make better design decisions to differentiate their
products in the marketplace."

Using LabVIEW and NI PXI 24-bit sound and vibration hardware, engineers can
acquire up to 5,000 simultaneously sampled channels of acoustic, vibration,
noise and dynamic pressure measurement data. By integrating I-DEAS Pro, they
can perform extensive on-line or post-processing analysis on this data with
tools designed specifically for sound and vibration applications.

To incorporate these measurements into early stages of design, MTS I-DEAS
Pro provides seamless integration with leading design and simulation tools
such as MSC.Nastran and MSC.ADAMS. Engineers can use the measurements for
material, component and system characterization, test-based empirical
component models, model verification and model optimization. This helps
engineers identify design limitations early in the design cycle and more
easily validate designs prior to prototype construction, greatly reducing
time to market and improving the usage of virtual and physical tests.

"The integration of the NI LabVIEW and MTS products empowers design
engineers to better validate next-generation NVH designs," said Mihir Ravel,
NI vice president of technology and corporate development.

"By combining the extensive experience of MTS in NVH design with our
expertise in measurement and control, engineers can seamlessly measure,
analyze and visualize noise and vibration earlier in the product development
cycle. This is a significant step in our initiative to reduce design time by
integrating LabVIEW into our customers' design flow."

The companies will demo their integrated solutions at SAE NVH 2003 in
Traverse City, Michigan at the MTS booth (#509), the MTS Partner Suite
(Tower Suite #1259) and the National Instruments booth (#513). Readers can
download a set of example programs for integrating LabVIEW and I-DEAS Pro on
