Abstract: This paper studies the motion of a rotational tethered satellite system flying around collinear Lagrangian points of the Earth-Moon system. Equations of spatial motion of the mass center and the tether libration are deduced, ...

Abstract: Gyroelastic body refers to a flexible structure with a distribution of stored angular momentum (called gyricity). In previous studies, it was assumed that each volume element of the structure possesses an infinitesimal ...

Abstract: This paper describes a fault-tolerant decoupling-control algorithm for spacecraft incorporating single-gimbal control moment gyroscopes (SGCMGs), simultaneously considering the SGCMG rotor and gimbal faults. Double-loop ...

Abstract: A novel two degree-of-freedom (2-DOF) parallel mechanism with remote center-of-motion (RCM) is proposed for minimally invasive surgical applications in this paper. A surgical manipulator with expected three-rotation and ...

Abstract: Artificial reefs (ARs) are one of the key anthropogenic constructs used to restore offshore fishery resources and recover the ecological environment. However, many ARs lose their stability and function due to scour. To ...

Abstract: Waste vegetable oil cold mix recycling technology can massively improve the resource utilization rate of solid waste in the road construction industry. This process can also reduce energy consumption and environmental ...
