About this Webinar!
The development process of military vehicles differs significantly from that of passenger and commercial vehicles, including different ride and handling requirements that must be satisfied. For example, the ride specification includes passes over half-rounds at various heights during which no occupant can be exposed to more than 2.5G vertical acceleration. For stochastic roads the absorbed power must be less than 6W. For each of these events, a threshold and an objective speed is specified. Handling requirements includes a range for the understeer gradient and a maximum roll gradient. Besides these explicit specifications, a good ride and handling balance is desired.

With tougher requirements for each year, it gets progressively harder to tune the vehicle suspension. With decreased development times and longer lead times for components such as springs and complex damper systems, the need for multi-event or multi-disciplinary optimization is increasing. By coupling Adams and Adams/Car with HEEDS/MDO to perform the multidisciplinary optimizations, Pratt & Miller designed, developed, and built a new vehicle design in 12 weeks, with the suspension element taking less than six weeks.
