Component-Level Crash Optimization Within a System Environment
Ronald C. Averill, Praveen Halepatali, Ranny Sidhu · Applied Mechanics · 2004
A new methodology is introduced to drastically reduce the time and effort required to perform vehicle crashworthy design optimization on components or subsystems whose performance is strongly coupled to that of the complete system to which they belong. The current approach reduces the CPU time for such design studies by a factor of 101 – 103, depending upon the problem definition. The main advantage of the current approach is that potentially thousands of design iterations can be performed in about the same amount of time required to perform a few (4–8) system level evaluations. With this approach, engineers can perform design studies and thoroughly explore new design concepts that were previously ignored due to their computational expense.
