    Simulation of Offshore Wind Turbine Blade Docking Based on the Stewart Platform

    Yi Zhang*, Jiamin Guo, Huanghua Peng

    Energy Engineering, Vol.120, No.11, pp. 2489-2502, 2023, DOI:10.32604/ee.2023.029496 - 31 October 2023

    Abstract The windy environment is the main cause affecting the efficiency of offshore wind turbine installation. In order to improve the stability and efficiency of single-blade installation of offshore wind turbines under high wind speed conditions, the Stewart platform is used as an auxiliary tool to help dock the wind turbine blade in this paper. In order to verify the effectiveness of the Stewart platform for blade docking, a blade docking simulation system consisting of the Stewart platform, wind turbine blade, and wind load calculation module was built based on Simulink/Simscape Multibody.

    Vibration Isolation for Sensitive Payloads of Spacecrafts Via Stewart Platform With the X-Shape Supporting Structure

    Xin Wang1,*, Xiaokui Yue1, Honghua Dai1

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.21, No.2, pp. 25-25, 2019, DOI:10.32604/icces.2019.04851

    Abstract With the rapid development of space technologies, the requirements of precise pointing and extreme stability increase a lot for spacecrafts. For some spacecrafts, sensitive payloads, including space telescopes, imaging sensors, space-borne optical interferometers are essential for the missions, which require a relatively quiet working environment. Generally, a spacecraft includes multiple instruments, including reaction wheels, cryogenic coolers, control moment gyroscopes and solar array drives, which can produce micro-vibrations. However, the micro-vibrations from the spacecraft and orbital perturbations both have a serious influence on the performance of sensitive payloads. For the sensitive payloads, performance requirements of low… More >
