Evaluation of Thermal Condition of Turbocharger Rotor Bearing
TL;DR: In this article, the effect of eccentricity on the pressure distribution in a thin lubricating layer of a non-Newtonian fluid was considered, and the distribution of temperatures and pressures in the lubricant layer was constructed taking into account the rheological properties of the lubricants.

Metaheuristic Algorithm-Based Vibration Response Model for a Gas Microturbine
TL;DR: In this article , measurements of the amplitude of vibration in the radial direction in a gas microturbine were analyzed using different rotational frequency and temperature levels, and a response surface model was generated using a polynomial tuned by the Jaya metaheuristic algorithm applied to the averages of the measurements, and another on the whole sample, to determine the optimal operating conditions and the effects that temperature produces on vibrations.

TL;DR: In this article, a dynamic balance compensation method for a rotor with an asymmetric radial structure is proposed, which integrates a left balance tool and a right balance frame as an integral component, through the overturn compensation operation and staticbalance operation of the two integral components, the additional unbalance amounts of the right balance tool, and thus the problem of large fluctuation of the unbalance amount in the dynamic balance measurement of a rotor overturn angle can be eliminated.
