Laboratory testing of active electromagnetic near constant force suspension (NCFS) concept on subscale four corner, full vehicle test-rig

摘要

In March of 1995, the University of Texas at Austin Center for Electromechanics (UT-CEM) began work on developing active suspension control algorithms for four-wheeled, off-road, rough terrain vehicles. To serve as a test platform to validate simulations, a four corner test-rig, representing a military HMMWV at one-third scale, was designed and fabricated. Multiwheel control algorithms were developed, based on single wheel concepts previously described in SAE publications. The four-wheel test-rig performance compared well with single-wheel test performance, showing that the active suspension concepts developed by UT-CEM, which do not require advanced terrain knowledge (i.e., no "look-ahead"), are compatible with full vehicle control.
