Effectively tracking down sound and vibration problems is a process that
benefits from structured thinking. By tracing problems such as road noise
from a tire from its source through the system, the process can be broken into
manageable pieces that a product development team can understand, analyze and
control.
That’s the basic concept developed in a series of free technical seminars
sponsored by MTS Systems Corp. The seminars present what the MTS
Consulting Group calls the “Source-Path-Receiver model” as a methodology for
dealing with sound and vibration concerns. Using a series of case studies
and demonstrations, the seminar provides design engineers a framework for
systematically addressing these issues.

Source-Path-Receiver Model
“The Source-Path-Receiver model is a way to look at a system and analyze
S&V concerns,” says Paul Goodes, Senior Consulting Manager for MTS
Systems. “This process takes full system problems and breaks them down
into smaller, manageable chunks.”
Using the tire noise example, Goodes explains how “road noise goes through
the suspension, the body, interior packaging and eventually gets to the person
in the vehicle.” But by looking into the problem in greater detail,
individual subsystems such as the suspension system can be broken into separate
Source-Path-Receiver models to accurately pinpoint problem areas for
resolution.
Goodes says that the seminar covers the tools available to support that
process, and also the benefits customers can gain by moving their view of sound
and vibration concerns from troubleshooting, to system validation and
design.
Sound and Vibration
Application Examples
The three-hour seminars (9:00 AM to 1:00 PM, including a free lunch) utilize
three case studies and demonstrations to explore the Source-Path-Receiver
model. The case studies have been designed to look at three distinct
areas: troubleshooting (refrigerator noise), system validation (an
aircraft braking system) and a design use case (DC motor seat track noise in a
vehicle).
A key component of the seminars is exploring software tools such as MTS’
I-deas Pro Software. This software package is used to acquire, measure and
analyze sound and vibration test data, and evaluate the effects of forces on
mechanical products or structures. Engineers can use the test data that
I-deas Pro collects to effectively diagnose and solve sound and
vibration-related problems, and it provides scalability by supporting more than
1,000 dynamic channels of data.
Another software tool covered during the seminar is Sound Quality, which
provides engineers with a first step to diagnose objectionable sounds and
improve sound quality.
Target
Audience
The seminars are specifically designed to educate ground vehicle, aerospace
and electromechanical system engineers about a wide array of advanced tools and
techniques for optimizing sound, vibration and durability testing
processes. Led by MTS experts and using leading-edge application examples,
the seminars will help attendees better understand how advanced MTS software
solutions and consulting services can help improve test processes by
establishing a more integrated product development environment.
