Abstract Tire vibration modes are known to play a key role in vehicle ride, for applications ranging from passenger cars to earthmover equipment. Inputs to the tire such as discrete impacts (harshness), rough road surfaces, tire nonuniformities, and tread patterns can potentially excite tire vibration modes. Many parameters affect the frequency of tire vibration modes: tire size, tire construction, inflation pressure, and operating conditions such as speed, load, and temperature. This paper discusses the influence of these parameters on tire vibration modes and describes how these tire modes influence vehicle ride quality. Results from both finite element modeling and modal testing are discussed.

This paper highlights the use of the finite element technique for analyzing stress and displacement distributions in wheels of automotive vehicles when subject to the conjoint influence of inflation pressure and radial load. The most commonly used considerations in the design of the rotating body are elucidated. A potentially viable technique for finite element modeling of radial wheel, subjected to loading, is highlighted. The extrinsic influence of inflation pressure on performance of the rotating body, that is, the wheel, is rationalized.

The Finite Element Modeling has been achieved for two dissimilar pipes welded by friction stir welding for given operating conditions and cases. Moreover, this analysis has been carried out to find the effect of hydrostatic pressure test on the welding area of the pipe by ANSYS Workbench software. In this study dissimilar materials of different pipes were used for FSW, which they were joined as 6063 aluminum alloy pipe with 6082 aluminum alloy pipe and C36000 high-leaded brass pipe with C12200 copper alloy pipe. In this study six parameters were used and with those parameters, eight (8) cases were welded and examined with hydrostatic tests and tensile test. The process was accomplished by varying one of the parameters (rotation speed) and keeping the others as constants.
