Abstract: Considering both nonlinear oil film force and unsymmetrical stiffness, this paper presents a mechanical model of a generator-bearing system. The complex mode synthesis method is used to reduce ...

Abstract: Different countries adopt different values of thermal expansion coefficients for steel cables in their design specifications, which results in the inconsistency for the design of prestressed structures. Therefore, a ...

Abstract: Steel cable is the key component of prestressed steel structures. However, the thermal expansion coefficients of steel cables have not been adequately evaluated yet. This paper presents an experimental study on this topic. ...

Abstract: To investigate the effect of oil film force on a geared rotor system, a short journal bearing model was applied to represent nonlinear oil film force. A dynamic model of the geared rotor ...

Abstract: It is noticed in a few steam turbines that there are a pad temperature rise of more than 10°C and a radial journal movement of more than 50 μm in the bearings adjacent to control ...

Abstract: A nonlinear dynamic model is developed for a rotor-bearing system with radial steam force due to partial admission, taking into account the prediction of subsynchronous instability of a steam ...

Abstract: In the construction process of construction engineering, there exist a complex construction site layout and multiequipment collaborative work. If a reasonable construction plan cannot be made quickly and accurately, the ...
