Effect Of Temperature

In this paper, the flow and heat model of high pressure rotor (HPR) has been established in condition of nature convection at different parking times. The flow and temperature fields of the HPR were studied by using CFD. Moreover, the continuous finite element model with multiple nodes of the rotor system was established considering the asymmetric temperature effect. Comparison of different models between ignoring and considering temperature fields was employed in detail. The calculated results show that the vibration amplitudes are increased and the orbits become disordered when the parking temperature field is considered for the HPR. In the frequency spectrum, there are abundant frequent components caused by temperature and rubbing force and the vibration characteristics considering temperature effect are more complicated than ignoring it for the HPR.

Abstract A finite element model was developed to simulate the tire-rim interface. Elastomers were modeled by nonlinear incompressible elements, whereas plies were simulated by cord-rubber composite elements. Gap elements were used to simulate the opening between tire and rim at zero inflation pressure. This opening closed when the inflation pressure was increased gradually. The predicted distribution of contact pressure at the tire-rim interface agreed very well with the available experimental measurements. Several variations of the tire-rim interference fit were analyzed.

Torsional Analysis

Abstract A three-dimensional (3D) beam finite element model was developed to investigate the torsional stiffness of a twisted steel-reinforced cord-rubber belt structure. The present 3D beam element takes into account the coupled extension, bending, and twisting deformations characteristic of the complex behavior of cord-rubber composite structures. The extension-twisting coupling due to the twisted nature of the cords was also considered in the finite element model. The results of torsional stiffness obtained from the finite element analysis for twisted cords and the two-ply steel cord-rubber belt structure are compared to the experimental data and other alternate solutions available in the literature. The effects of cord orientation, anisotropy, and rubber core surrounding the twisted cords on the torsional stiffness properties are presented and discussed.
