Noise source identification on rolling tires by sound intensity measurement.

Temperature prediction of rolling tires by computer simulation

A numerical procedure has been applied for investigating the temperature distribution in a smooth tread bias tire of a light truck, operated under different speeds, pneumatic pressures, and loading conditions. Prior to simulation by the finite element analysis, two separate sets of testing, namely dynamic mechanical testing and material testing, have been conducted in relation to the evaluation...

Self-excited Lateral Vibrations of Rolling Tires

In this study, a low degree-of-freedom mechanical model of a rolling tire is constructed, in which the lateral deformation of the contact patch and tire carcass is considered. The so-called delayed contact patch model is implemented and combined with a simple tire carcass model. The interaction between the contact patch and the carcass together with the lateral mode of the attached suspension s...

Identification of static distortion by noise measurement

ELECT Many active devices exhibit gross nonlinearity, which is traditionally mitigated using negative feedback. In those cases where negative feedback is not desired, compensation for the distortion can be carried out at the postprocessing stage by inverting the transfer function of the device. A new technique is demonstrated where the inherent noise in the system is exploited to estimate the r...
