Wireless Monitoring of Automobile Tires for Intelligent Tires
This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibil...
متن کاملNondestructive Evaluation of Automobile Tires by Electronic Speckle Pattern Interferometry
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...
متن کاملCentrifugal force in Kerr geometry
We have obtained the correct expression for the centrifugal force acting on a particle at the equatorial circumference of a rotating body in the locally non-rotating frame of the Kerr geometry. Using this expression for the equilibrium of an element on the surface of a slowly rotating Maclaurin spheroid, we obtain the expression for the ellipticity (as discussed earlier by Abramowicz and Miller...
متن کاملSome Observations on the Effect of Centrifugal Force in Man.
ANY flight manoeuvre, whether simple or complex, imposes varying degrees or types of acceleration upon the aircraft and the crew. Centripetal acceleration is developed when an aircraft is moving in a curved path, and its value is directly proportional to the square of the angular velocity. For a constant indicated air-speed, the centripetal acceleration is inversely proportional to the radius o...
متن کامل”Centrifugal force: A gedanken experiment”—new surprises
A recently proposed gedanken experiment [G.Z. Machabeli and A.D. Rogava. Phys. Rev. A 50, 98 (1994)], exhibiting surprising behavior, is reexamined. A description of this behavior in terms of the laboratory inertial frame is presented, avoiding uncertainties arising due to a definition of a centrifugal force in relativity. The surprising analogy with the radial geodesic motion in Schwarzschild ...
