High Speed Engineering Vehicle

This project demonstrated the performance and ruggedness of the DSI suspension system in the
HSEV, a military/commercial multi-purpose construction vehicle. The HSEV concept originated
from the Australian Army’s need for a multi-function, high mobility engineering vehicle capable of
high speed travel over various road and rough terrain surfaces without need of trailered transport.

In response, DSI designed a compressible fluid system for the twelve ton HSEV consisting of four
compact struts, one for each wheel, that provided high performance spring and damping under all
ride conditions. To provide a highly stable platform for various construction tasks, the front struts
can be selectively locked out by the vehicle operator. After four years of rigorous and successful
testing and evaluation by the Australian Army and ATEA, this prototype vehicle earned top honors
as one of the fastest, most mobile engineering vehicles in the world.
