چکیده
The nonlinear thermo-mechanic coupling effect refers to the interaction between dynamic characteristics of a dual-rotor system and thermal an intershaft bearing. In this paper, is proposed studied by operating radial clearance load A model under bearing established considering factors such as Hertzian contact force obtained based on responses system. Based this, proposed. attained according temperature field presented connecting model. results solved numerical iteration show that are deeply coupled with bearing, become weaker. turn, complex affects due Furthermore, closely related decreases increasing temperature, decreasing initial clearance, sharply in resonance regions. Thus, “negative clearance” may affect which endangers operation rotor Moreover, stronger ambient increases. paper provide insight into mechanism new theoretical guidances for thermodynamic design
