Hydraulic Actuated Roll Inhibited Active Suspension for the Army

Vehicle stability is typically compromised when the high mobility, payload and transportability requirements placed on military tactical vehicles are dependent on conventional passive suspension technologies. Rod Millen Special Vehicles (RMSV) is confident that with the proper selection and development of an advanced suspension system for military tactical vehicles, improved stability, safety and performance can be realized. Electronically controlled suspension systems allow the integration of the suspension into vehicle area networks, supporting prognostics and embedded diagnostics. For this effort, RMSV will update its internal database of advanced suspension technologies and perform a systematic high fidelity dynamic analysis to evaluate the relative performance of each candidate technology. The performance of RMSV's prior bolt-on active/semi-active suspension systems will also be assessed in the context of this evaluation. Using HMMWV as a common platform for evaluation allows real-world test data to be used to assess the performance of many candidate suspension systems. A comprehensive trade study, based on dynamic analysis and field test results, will support the identification and development of an optimal suspension technology which will result in improved safety, performance, mobility, driver control and passenger isolation at minimal cost for the Army's fleet of future tactical vehicles.
