TL;DR: The results showed that the proposed decoupling compensation method for damping improvement of the electrohydraulic control system with multiple actuators reduced velocity and pressure oscillations under different working conditions, so the dynamic performance is improved for the multiactuator system.

TL;DR: In this article, a novel electromagnetic variable stiffness isolator that achieves bidirectional stiffness regulation was proposed, which can not only ensure the vibration isolation performance in working frequency zone that is relatively far from the natural frequency but also can realize high-damping-like effect for shock response attenuation, without introducing any additional damping components that may complicate the system.

TL;DR: In this paper , an active learning Kriging (ALK) based reliability analysis method for a multi-output structural system by using a multiple response Gaussian process (MRGP) model was proposed.

TL;DR: In this paper , the effect of gear installation and manufacturing errors on the non-inertial coefficients under two maneuvering conditions was analyzed, and the results indicated that the effect has significant influence on the changing trend of non-INERTial coefficients with the gear installation.

TL;DR: In this article , a dynamic model of a high-speed train gear transmission system was established under the conditions of time-varying meshing stiffness and time-changing meshing error, and a frequency spectrum analysis of the vibration at the key nodes of the model was carried out.
