Explicit solutions of the two-dimensional floating body problem (bodies that can float in all positions) for relative density ρ 6= 1 2 and of the tire track problem (tire tracks of a bicycle, which do not allow to determine, which way the bicycle went) are given, which differ from circles. Starting point is the differential equation given by the author in [12, 8]. The curves are also trajectori...

A steering by wired haptic system based on disturbance rejection control techniques is presented. High gain Generalized Proportional Integral (GPI) observers are considered for the estimation of tire and steering wheel dynamic disturbances. These disturbances are on line canceled to ensure efficient tracking between the commanded steering wheel angle and the tire orientation angle. The estimate...

Inflatable robotic rovers (IRRs) are a promising concept for long-range exploration and access to high-risk areas on planetary surfaces. Through inflation or expansion of their locomotion elements, inflatable rovers can achieve extraordinary terrainability not possible by other conventional mobility systems while maintaining respectable travel speeds. Early work by NASA's Jet Propulsion Laborat...

For future advanced active safety systems, in road-vehicle applications, there will arise possibilities for enhanced vehicle control systems, due to refinements in, e.g., situation awareness systems. To fully utilize this, more extensive knowledge is required regarding the characteristics and dynamics of vehicle models employed in these systems. Motivated by this, an evaluative study for the la...

To produce thin grooves in the tread portion of tires, tire molds contain a multitude of sipes, which are thin metal inserts that project into the tread rubber during molding and curing. The geometric design and location of sipes is based on tire performance as well as appearance. A completèfamily' of tires, typically consisting of a dozen or more tire sizes with similar tread designs, will req...

high volume of waste tires, problems associated with their disposal, aesthetic problems, and the expansion and innovation of reuse of used tire products is being addressed aggressively. Chipped or shredded tires are being used for a wide variety of products, including playground covers, doormats, roadbed, fill, shoes, and aggregate substitute in septic system drainfields. This Analysis of Tire ...

Electronic speckle pattern interferometry (ESPI) was used for the evaluation of mechanical properties of automobile tires. The tire on wheel disc was fixed on the holder and its vibration was generated by loudspeaker. Vibrational field of the whole tire was visualized by ESPI and recorded into PC. Natural frequencies of various vibrational modes were measured and results were compared with thos...
