From Regenerative Suspension to Electromagnetical Suspension
With regenerative braking technology reaching maturity, manufacturers are studying other forms of energy regeneration, amongst these: regenerative suspension. Although there have been several regenerative shock absorber developments over the past decade, including linear-tubular electric motors and hydraulic actuator based systems, cost and...

American company, Edison 2 LLC, recently unveiled their latest Very Light Car (VLC) at the Henry Ford Museum’s Driving America exhibit. The VLC’s low, wide stance with cycle gear wheels (Not enclosed in the body) is made possible because the patented suspension system, including springs, dampers and universal joint, resides inside...

In an ongoing endeavor to control ride height several teams have come up with a passive system which meets the FIA’s regulations: Namely the Front and Rear Inter-Connected (FRIC) system.

Although details are closely guarded it is believed the FRIC system, with the hydraulic actuator (lower arrow) housed in the sidepod, displaces... Full Content »

Active suspension first found its way into Formula one racing in 1981 when teams were searching for a means of using "skirts" fitted to the sides of the cars to increase aerodynamic downforce and improve handling. Crucial to the success of the design was a controlled ride height: Enter Lotus’ first ever active suspension.

These early... Full Content »

Cost-Effective Skyhook Control for Semiactive Vehicle Suspension Applications
Skyhook control, which is now widely applied to vehicle suspension control, requires two sensors to measure sprung mass acceleration and relative displacement, respectively. In the practical implementation, these two measurement signals are converted into corresponding velocities; then per the skyhook control policy the velocities are employed to... Full Content »
