electromechanical actuators (EMAs), which can directly convert electrical energy into …

The neglection of thermal-mechanical interaction of the high-speed motorized spindle
system may lead to modeling errors of thermal and dynamic characteristics. In this work, the …

Existing maintenance optimization models for single-component repairable systems are
extensively studied. However, maintenance optimization in multicomponent reparable …

Modern tendency of machine tools design requires more accurate model to predict the
system dynamics, in order to anticipate its interaction with machining process. In this paper …

The surface morphology has an important influence on the dynamic response and bolt
loosening of bolted joints. In this paper, based on the fractal contact model, an original …

The nonlinear characteristics of kinematic joints for the column-spindle system have a
significant influence on machining accuracy. This paper proposes a comprehensive …

The dynamics of the ball screw feed system is very important in high-precision machining of
CNC machine tools. However, the existing literatures rarely study the dynamic behaviors of …

For the asynchronous motorized spindle directly driven by the induction motor, the load-
dependent slip ratio determines that its transient characteristics are sensitive to load. For the …

Owing to the geometric errors, preload of ball screws usually exhibits a two-stage degrading
characteristic during operation, which is taken as the running-in stage (the first stage) and …
