... cohesive and harder. As shown in Fig. 5a , the coefficient of linear thermal expansion of GSG-Al for temperatures between 25 °C (298 K) and 185 °C (458 K) was found to be similar to that of aluminum. As noted, the GSG-Al has 50% aluminum by mass. Noticing the effects of expansion at higher...

... provides a controllable heat source and thermocouples record the temperatures on the shaft and GFB housing. For increasing shaft temperatures (up to 188 ° C ), increasing static loads (0–133 N) are applied to the bearing and its deflection recorded. In the test configuration, thermal expansion of the GFB...

... calculations. The displacements of the inner surface of the bushing δ h PB θ , z are deduced by multiplication of the compliance matrix by the pressure field, and then added to the film thickness. Thermal deformations are considered by taking into account the thermal expansion...

... on the thermal expansion coefficients of shaft and sleeve. The clearance of the upper journal bearing at the rotating speed of 7200 rpm decreases from the undeformed clearance of 2.5 μm to 1.98 μm at the elevated surrounding temperature of 58.7°C because the thermal expansion coefficient of the shaft is larger...

...J. Y. Jang; M. M. Khonsari Thermoelastic instability (TEI) is known to be directly related to the occurrence of hot spots in friction systems, such as brakes, seals, and clutches. TEI is a failure process where the local frictional heat, thermal expansion, contacting pressure and temperature grow...

... coefficient and thermal expansion coefficient are performed to gain insight into the phenomenon of TIS. A statistical procedure is applied to the simulated results and an empirical relationship is derived. Good agreement between the empirical and published results attests to the capability of the model...

... that cupping moves in the positive direction for an increase in the substrate’s Young’s modulus in the transverse direction for MP and ME tapes. An analytical model demonstrates that increases in temperature and front coat thermal expansion coefficient leads to cupping movement in the negative direction...

...B. K. Gupta; Kenneth Young; Sameera K. Chilamakuri; Aric K. Menon The magnetic/mechanical spacing between the transducer and the disk significantly decreases due to thermal expansion of pole tips at stressed high temperature and high humidity tests. The protruded pole tips and alumina overcoat can...
