Just Like Riding a Bike Altair - Startup Program Improves 3D-Printed Structures at Urwahn Bikes

Urwahn Engineering GmbH is a startup in the biking sector. While bikes must meet many requirements to pass globally recognized test and load case scenarios according to DIN ISO 4210 safety standards, they must also be light to reduce raw material usage and create the best possible user experience. For this aim, simulation has always played a key role at Urwahn, a team that strives to maximize functionality and performance by using state-of-the-art tools. Under the Altair Startup program, Urwahn received access to Altair® Inspire™. To meet the DIN ISO 4210’s safety requirements, they simulated five load cases on the steel frame structure, studied the behavior of the single 3D-printed parts, and explored the impact of the material distribution on the overall system behavior. Inspire’s integrated topology optimization solver enabled Urwahn to push the material usage limit, reducing weight and costs while keeping stiffness and other boundary conditions on target.
