Abstract
The authors propose a new basic suspension model which isolates longitudinal shocks and vibrations. In the new model, the wheel is supported by a crankshaft and has a degree of freedom of circular motion. Application of this new basic model to aircrafts, automobiles, trains, and motorcycles overcomes the limitation of the performance against longitudinal impact. This study focused on the as-yet-unresolved problem of aircraft landing gears, which is acceleration impact on the wheels.
