Design Crash Simulation

MAN verifies and validates the crash properties of a sandwich bus roof in a dynamic overturn. The company has thus demonstrated that simulation methods are suitable for assessing the crash resistance of functionally integrated lightweight components.

Approval of Crash Simulation

The constantly growing requirements regarding comfort, safety and environmental compatibility are a driving force behind the development of vehicles. This also applies to commercial vehicles, in particular buses for passenger transport. The development of new technical solutions should also meet the manufacturer’s economic objectives. The following paper describes the development and application of a very large functionally integrated lightweight construction element using the example of a bus roof in sandwich construction. As part of the body-in-white structure of a bus, the component must also meet the technical requirements with regard to crash resistance and fatigue strength. Weight considerations are also...
