Simulation of Coach Rollover Performance using HyperWorks - Safer and Lighter by Virtual Design

Alexander Dennis Ltd (ADL) is the UK’s leading bus and coach manufacturer, employing around 2000 people at facilities in the UK, continental Asia and North America. ADL produces a wide range of innovative and fuel efficient, low floor single and double deck buses, plus a full portfolio of coaches. They required a method that would automate the process of setting up and preconditioning a vehicle Finite Element (FE) model in order to simulate a vehicle rollover while still complying with the required industry ECE R66 standard. ADL selected Altair’s HyperWorks tools in order to implement the required methodology and RADIOSS was used as the solver for this project.
