Innovative Chassis

Dyno Testing Solutions

for the Future of

Mobility

Chassis dyno testing systems are essential

for vehicle development and validation.

At AVL, AVL Zöllner GmbH is the company

in charge of this area. The company has

been part of the AVL Group since 2001 but

has been manufacturing sophisticated test

systems since the 1960s.

ith more than 1,400 installed systems, AVL Zöllner is

the undisputed market leader in chassis dyno testing

systems. Headquartered in Bensheim, Germany and

with a production facility in Hranice, Czech Republic, the com-

Tany reali^es amFitioYs veLicle develoTment and certification

projects around the world. It also has an impressive service

offering, which is fully integrated into the customer-focused,

global AVL service organization.

“In the past, emission legislation was the main driver of our

FYsiness. 8Lese days it is electrified and alternative drive

technologies that are placing new demands on development

and certification. ;e Lave aligned and develoTed accordingly

and offer state-of-the-art solutions,” explains Arnold Berger,

Managing Director of AVL Zöllner GmbH.

%n e\amTle oJ an innovative develoTment and certification

solYtion in tLe field oJ electromagnetic comTatiFility is

AVL ROADSIM™ EMC. The test system was developed

in collaboration with Rohde & Schwarz – the technology

leader in tLe field oJ )1' measYrement tecLnology Ɓ and is

characterized by fully integrated measurement technology.

With AVL ROADSIM™ NVH PREMIUM and AVL ROADSIM™

NVH COMPACT, the current program includes two NVH (noise,

vibration, harshness) testing solutions. All test systems comply

with current and future requirements – from mechatronics and

measurement technology to automation, methodology, and

automated lab management. “We are the benchmark in many

areas – for example, determining the range of electric cars.

This requires much higher accuracy these days than in the

past,” emphasizes Berger.

The innovation and quality of AVL Zöllner also appeal to

customers, as proven by the latest GEELY Quality Award.

AVL Zöllner kitted out the major customer’s climatic wind

tunnels with testbeds. This example also highlights the broad

spectrum of the portfolio – from two wheelers to passenger

cars and heavy-duty applications. A new system solution in the

latter area stands out: a one-of-its-kind regulation concept on

the global market for testing multi-axle vehicles, which covers

major future customer requirements in the HD segment.

The comprehensive portfolio meets the requirements of

established OEMs and new market players.

In the after sales area, the high number of installed chassis

dyno testing systems ensures stable growth: With new

AVL Zöllner’s testbeds are generally characterized by robust

mechanisms and a long lifetime, which is a major advantage in

terms of sustainability.

Another important success factor according to Berger is the

synergetic collaboration with a variety of AVL areas: “No one

else on the market can offer this extensive expertise.” The

exchange also results in hardware and software becoming

increasingly interlinked and optimally aligned for relevant

aTTlications. 8Le oYtcome Feing consideraFly LigLer Fenefits
