Testing?vertical?dynamics?of a Audi A8 on a quarter-car test rig
For the last two weeks I have been in an automotive engineering class here at TU Braunschweig. University classes in Germany are structured differently from those in the U.S. becasue 100% of your grade is based on the final test at the end of the semester. Yikes! Needless to say, it felt like I was back at Mines studying last?Thursday night.?But besides stuffing my head full of gear ratios, types of transmissions and breaking circuits, we did learn a lot of?interesting?things about cars.
Each day we had lectures about subsystems of the car, and without knowing it, the teachers often used one phrase when answering these types of questions: ?Why do you put the anti-roll bar on the back wheel?? ?Why would you use louvers?? Your geeky professor just looks at you and states the obvious: ?Oh! Because it?s more fun to drive.?
The Automotive Institute at TU Braunschweig also has a pretty neat testing facility, and some awesome cars to go along with it. After learning about the infrared cameras and other fancy features, it was fun to see them on an actual 100,000 euro car.
They showed us how to perform tests for vertical dynamics?on a car chassis using quarter-car test rigs. We saw the tests for vibration and damping on an Audi A8. I never thought I would have seen a Fourier series put to use on an Audi but, sure enough, now I have.
We also went to the Autostadt, which is composed of museums and exhibits of all the different Volkswagen cars. It includes?pavilions?for Audi,?Porsche and?Lamborghini?companies owned by?Volkswagen. We ran around designing out own Audi, looking at classic cars and sitting in some of the most expensive Porsches. For me it confirmed that someday I am going to spend an unreasonable amount of money on a car.
