Simulations of Arctic and Desert Driving
In any case, eCON showed how important it is to have the right expertise to set test specifications and effectively use the company’s high-quality test stands in new and innovative ways. At its headquarters in Weinheim, Freudenberg Sealing Technologies had a test bay with a wide range of test stands. “Using these stands, we try to approximate reality as closely as possible,” said Robert Leins, Test Facility Manager. “To test our Simmerrings, we can simulate driving in the Arctic, the desert and through water.”
With Freudenberg Sealing Technologies’ simulations mimicking a wide variety of conditions in motors, wheel bearings and other applications, it is possible to demonstrate the effectiveness and the efficiency of its innovations. Leins and his staff also perform tests for manufacturers of equipment, vehicles and fluids who set their own specifications for the tests. This reduces the need for tests in real vehicles. “In the end, it is more practical to test in test stands than to wait until a wheel bearing has racked up 300,000 kilometers (186,000 miles),” Leins said. “At our test stands, we work with high rotational speeds, pressures and temperatures, just as they occur in real life. When materials are tested in this way and solutions withstand the stress tests, it can be assumed that they will achieve a specified lifespan in practice,” he said. The tests are significantly shortening the time it takes to attain reliable results. And if adjustments become necessary, they can be made more quickly.
