Nick Jordan, technical engineering manager at a well-known military steering specialist, addresses the need for data-driven design in the manufacture of military vehicles


ata is a critical asset for military organisations, but it is only valuable if it’s meaningful and used


eff ectively. This may explain why the military vehicle industry is proactively responding to evolving security threats and upgraded technologies. It starts with real life military vehicles.


Strain gauging equipment is added to test vehicles to calculate forces and collect meaningful design data for steering and suspension systems. By using data generated from real-life vehicles, design engineers can make

more informed decisions on how to best manufacture a military vehicle. It is not necessarily the static values of the load or frequency data that is of most concern in the design process, considering that most military vehicles are designed to go above and beyond the actual loads and frequencies they will face. Rather, it’s the dynamic nature of the vehicle’s activity - the varying loads, changeable frequencies and irregular abusive loads that occur during the vehicle’s life that should be a fundamental consideration.


This use of real-life data takes this


dynamism from the qualitative realm, so engineers can use this when developing a vehicles design.


DATA-DRIVEN TESTING It goes without saying that the current considerations for human-driven military vehicles will also need to be brought into the new paradigm of autonomous combat vehicles. For instance, adverse weather conditions, such as sandstorms, black ice and dust can challenge even the best military vehicles in the industry. Without an
