HEAVY DUTY TESTING SYSTEMS

A wake-up call for your test bedsProductivity and high technology

The market for heavy-duty test beds is moving — and fast! The market is globalizing, and the environmental goals are increasingly ambitious.

For your testing centers, that implies:

- A greater diversity of standards that increase the number of test types to be performed, and their complexity: Euro 6, US transient, JE05, WHTC and more.

- Increased demands on productivity, test bed rotation, and operational maintenance.

And electrifi cation of the powertrain is rearing its head.

D2T is ready: Come discover our solutions!

Complete solutions for your testing needs Today and tomorrow

Our Heavy Duty test bed solutions are based on a three-pronged approach:

- Open and packaged test bed automation system

- Reliable and effi cient test bed equipment.

- Utilities of the test bed, designed by D2T as modules.

From our experience in Heavy Duty, we know how to dimension utilities according to power and dynamic needs.

We have developed for many years our own modular systems such as ventilation, extraction, combustion air, fl uids, electrotechnical, fl uids, gas outfi ts gas. This allows simple, functional and effi cient integration to realize your test beds.

Dynamometers and transmissionsDynamic and robust

The load machine and its components must drive very high-torque engines, and with lower and lower inertia. Now, responsiveness approaches that of the engine, compared to a ratio of 4 in the past. This means heavy stress on the shafts and the bearings.

To respond to this challenge, D2T has two advantages: a long design experience in dynamometers and a knowledge of shafts and ball bearings design drawn from aerospace.

High torque, low inertia

Automation and simulationThe reality of today’s testing center: Increasingly complex tests must be performed at a higher operational time of the test bed while ensuring reliable results. When you regularly have to perform 10, 20, 40 or more types of tests on 100 different test beds, it’s a challenge. The solution: Manage complexity in a simple way. And with no bugs. And never forget that it’s the people who are the life of the testing center. The majority of them are engine engineers, not IT experts. The D2T solution: we give them the key to their test beds.

Typical architecture

An open and scalable architecture

Test facility managementA testing center is made up of people and tools. The people work together, and the tools communicate among themselves. The information must be reliable and rapidly received by the people who need it.

At D2T, an efficient hot-line team thanking any claim though a global database

Permanent follow-up with:TMS: Bench status in real time, through a web applicationYields Metrics: measurement of the performance of the test facility

Test manager: database solution for MORPHEE which provides central handling, sharing, and protection of all test data for all co-workers. It is based on robust, powerful, and proven databases that easily adjust to customer specific data flows and models.
