The objective of this proposal is to demonstrate Fluid Ride LTD's patented Compressible Fluid Active Suspension Technology CFAST ability to improve soft soil mobility and mitigate road breakaway rollovers on a 10-37 ton wheeled vehicle. The US Armed Forces see too many roll-overs and missions compromised due to vehicles stuck in a no-goCFAST has shown the potential to improve through successful October 2012 CRADA shaker test and present SBIR Phase I virtual demonstration. CFAST Pump and Strut core technologies are now production-feasible: Fluid Ride can deliver affordable, durable and robust, high-performance active suspension systems. In this Phase II project, Fluid Ride will utilize the Phase 1 models + simulation results and will refine the model to simulate the actual vehicle selected, and continue to develop controls to walk or improve soft-soil mobility, and to sense and mitigate rollovers. Fluid Ride will then build a CFAST-equipped demonstration vehicle to prove functionality in the real world. Successful Phase II results will include real-world demonstration of CFAST's ability to successfully walk the vehicle out of soft soil and mitigate rollover.
