    Suspended Load Path Tracking Control Strategy Using a Tilt-Rotor UAV by M. A. Santos, B. S. Rego, G. V. Raffo, A. Ferramosca

    Published 2017-01-01
    “…An unscented Kalman filter (UKF) is designed for nonlinear state estimation of all the system states, assuming that available information is provided by noisy sensors with different sampling rates that do not directly measure the load’s attitude. Furthermore, a model predictive control (MPC) strategy is proposed for path tracking of the suspended load with stabilization of the tilt-rotor UAV when parametric uncertainties and external disturbances affect the load, the rope’s length and total system mass vary during taking-off and landing, and the desired yaw angle changes throughout the trajectory. …”

    ANALYSIS OF DYNAMIC LOAD STRENGTH OF WIND TURBINE ROOT BOLT UNDER TURBULENCE MODEL by HAN Wen, CHEN ChangZheng

    Published 2021-01-01
    “…In this paper,the connecting bolt between blade and pitch bearing of 2 MW wind turbine is taken as the research object,and a dynamic strength analysis model of blade root bolt of wind turbine is established under the conditions of three-dimensional turbulent aerodynamic load,gravity load and centrifugal force load. Under the condition of normal operation and partial bolt fracture failure,the stress distribution of blade root connecting bolt is obtained by finite element analysis.Compared with the traditional bolt strength analysis,this paper can get a more real trend of bolt stress change,the maximum stress value and its location. …”
