Environmental simulation at ATESTEO

Environmental simulation: Testing possibilites on the test bench

  • High temperature test
  • Thermal behaviour
  • Alternating temperature test
  • Low temperature test
  • Humidity

ATESTEO is the leading specialist in drivetrain testing for combustion engines, electric drive systems, and hybrid drive systems. With many locations right where the automotive industry develops transmissions, ATESTEO offers drivetrain testing services close to the customer. The simulation of environmental influences plays a large role during the development of automobiles. The earlier and more reliably components can be tested on the test bench for their behaviour in terms of temperature, humidity, and shock, the more powerful and durable the drivetrain will be.

Drivetrain optimisation through environmental simulation

The drivetrain of a vehicle is subject to a multitude of environmental influences throughout its service life. These influences characterise performance and service life; thus, their impact on the environment as well.

With methods of environmental simulation, ATESTEO tests the interaction between the drivetrain and its environment. The aim of environmental simulation is to discover relationships between causes and effects and to qualify parts or components for given environmental conditions.

The environmental simulation tests are concerned with the effects of the environment on:

  • Performance and functional behaviour of the test object.
  • Long-term behaviour and service life of the test object.
  • Reaction to the environment of the test object.

Environmental simulation on the test bench for all requirements

In addition to the existing classic stationary test benches, ATESTEO now offers new, modularly designed environmental simulation test benches which are installed compactly in mobile units.

In a total of eight different configurations, with one or two load machines and an optional climate chamber, the new test benches for environmental simulation from ATESTEO can be adapted rapidly at any time to the respective testing needs of the customer. A battery simulator is added to the environmental simulation of electric and hybrid drive systems.

Modular concept for environmental simulation test bench

The new and innovative test benches for environmental simulation from ATESTEO are set up in a mobile unit according to the needs of the customer. This allows the testing chambers to be flexibly extended and connected to one another. At this time, up to eight modular test benches can be made available simultaneously for various environmental simulation scenarios or different test objects.

Set-up of the modular environmental simulation test bench

  • Climate control unit for circulating air:
    • Two separate liquid coolant supply circuits
    • Separate climate box with two drive shaft outlets
    • Indirect temperature control of the test room
  • Battery simulator for hybrid drives
  • Cooling oil supply and conditioning
  • Possibility of external drive of test objects and components
  • Automation system PDES 5
  • Test chamber 1: W x L x H: 1500 x 1550 x 1000 mm
