Multi-disciplinary System Simulation for Model-Based Development

Customers share their success stories illustrating how Altair Model-Based Development technology, and especially Altair Activate™, help them design better products faster. These customers give special attention to simulating multi-disciplinary performance aspects of their products as a system-of-systems. Given the complexity of today’s smart products, this often involves a combination of mechanical, electrical & electronic, and/or software aspects – and thus leverages both 1D and 3D models simulated together.

Virtual Tryout - Digitalization for an Efficient Commissioning of Forming Tools

Presentation by Dr. Lars Penter, Head of Machine Technology at University of Dresden.

The life cycle of a forming tool consists of five major phases. It starts with the process and tool design followed by its assembly, the ramp-up and serial as well as spare part production. Due to every increasing system complexities, various simulation tools accompany today’s tool life cycle. A popular term in the current world of production is the “Digital twin”. It is a simulation model, which contains at least two sub-models of different physical disciplines, connects different time scales and regularly synchronizes data with the real system. Such a model must be a highly accurate white box model.The presentation will address the generation of a virtual twin on the example of the virtual try-out of forming tools. The simulation model employs RADIOSS (for forming process simulation), MotionSolve (for multi-body simulation of machine mechanics) or Activate (for more complex multi-domain modelling of mechanics, hydraulics and electrical components). Currently, the digital twin allows for computing the interactions between forming process and die cushion. This enables the calculation of correlations between die-cushion cylinder forces and flange draw-in. The presentation shows how optimizing these cylinder forces in HyperStudy benefits the final part quality and shortens real tool try-out time.
