NVH simulator software
VI-grade's (Canton,
Mich.) NVH Simulator
2021.0 is the latest
release of its NVH
Simulator software,
which incorporates
new features and capabilities
as well as
revises the pricing
model and product structure to enable easier use and accessibility.
Recently incorporated into VI-grade's automotive simulations
solutions portfolio, NVH Simulator solutions provide
automotive product development professionals with tools they
need to accelerate product development across a range of automotive
applications and from a single source. The NVH
Simulator solutions enable accurate experience of sound and
vibration data and comprise a comprehensive set of solutions
including desktop NVH simulators, full-vehicle static NVH simulators,
in-vehicle/on-road simulators, exterior sound simulators
and sound solutions providing accurate sound in concert with
any driving simulator. Engineers and designers can set and
achieve targets, assess design options, conduct benchmark
comparisons, design the sound of EVs and IC-engine vehicles
and communicate sound and vibration concepts and issues to
decision-makers with these solutions.

Adhesive transfer tape
3M (St. Paul, Minn.) Adhesive Transfer
Tape 6038PC is a pressure-sensitive adhesive
transfer tape suitable for use in
automotive interior applications.
According to the company, the doublesided,
acrylic adhesive is tested to SAE
J1756 specifications and offers adhesion
to many materials. This tape is 8.0 mils
(.20 mm) of adhesive coated on a 4.2
mil (.10 mm) polycoated kraft paper liner.
Specifically designed to be low fogging,
3M's Adhesive Transfer Tape
6038PC provides a strong bond on
many surfaces, including plastics, wood, foam, fabric and
metal. This adhesive transfer tape meets specifications of
automotive manufacturers, making it suited for use on interior
fabrics and panels. Recommended applications include
to attach a wide variety of vibration and sound-damping
materials, bond automotive interior anti-squeak fabric and
foam and attach interior panels.

Indoor pass-by solution
The BK Connect
Indoor Pass-by tool
from HBK (Egham,
U.K.) was designed
to help automotive
manufacturers ensure
their vehicles
comply with strict
pass-by noise regulations.
Although
pass-by noise tests
have typically been
performed outdoors, an indoor method now is also accepted
for type approval. According to the company, BK
Connect Indoor Pass-by software was created in line with
legal standards so it covers the full spectrum of pass-by
testing, making it suitable for automotive testing needs,
from conformance assessments to noise-source contribution
analysis. The software includes automatic measurement
plans, a pre-defined test setup, which can be uploaded
ahead of time to focus on test operation, plus the ability to
define source and indicator microphones for Source Path
Contribution (SPC) analysis. Test data is accessible on the
BK Connect Team Server for inspection, comparison, and
reporting using a Pass-by Data Viewer.

Air springs, hydro bushings
Vibracoustic's (Darmstadt, Germany) front
and rear axle air springs, as well as hydro
bushings, are used in the all-electric SUV
Hongqi E-HS9 from car manufacturer FAW
(Changchun, China). The air springs in the
Hongqi E-HS9 use a welding technology
that makes it possible to use both plastic
and aluminum for the air-spring top pot,
resulting in increased design flexibility and
reduced overall weight. This technology can
optimize the airflow under the car and
therefore contribute to a better passive battery
cooling in electric vehicles. The E-HS9
also is equipped with Vibracoustic's hydro bushings, which
help to improve handling and safety and reduce unwanted
vibrations. The bushings respond to road-surface excitation
and the integrated fluid adjusts the dynamic properties of the
bushings depending on these excitations to always provide a
smooth ride and best possible driving comfort for all passengers,
the company claims.
