What simulation changed on real programs
Both programs were modeled before any hardware existed.
Validating an autonomous tracked vehicle before cutting metal
Stratom, Inc.
- Problem
- No prototype yet, and a high cost for a wrong first build.
- Modeled
- Full-vehicle multibody model with track systems over terrain and obstacles, transient stress on the flexible frame.
- Result
- Design changes made from the model; the prototype build went ahead on time and under budget.
Predicting bucket loads on a machine that did not exist yet
A heavy-equipment OEM
- Problem
- Hydraulics to size at concept stage, and no machine to measure.
- Modeled
- Discrete element material simulation coupled to the machine model through the dig cycle.
- Result
- A power envelope for sizing the hydraulics while the design was still open.
“Darren brought our simulation capacity to an entirely new level. We engineered an innovative hybrid mining shovel and validated new design and controls concepts through simulation, without spending excess money on tests.”
Have a design to prove, or a problem to explain?
NDA-ready and US-based.
