The support towers are at the heart of wind turbines’ structural and operational stability, and because of their slender and flexible design, these are dynamic interactions between the aerodynamic forces, turbine functions, and environmental loads. This study introduces a simplified modeling approach using the Euler-Bernoulli beam theory to analyze the structural and dynamic responses of a 4.4 MW onshore turbine tower. **Topics:** Design, Dynamic analysis, Euler-Bernoulli beam theory, Modeling, Renewable energy, Wind turbines.

Studying and analyzing the dynamic behavior of offshore wind turbines are of great importance to ensure the safety and improve the efficiency of such expensive equipments. In this work, a tapered beam model is proposed to investigate the dynamic response of an offshore wind turbine tower on the monopile foundation assembled with rotating blades in the complex ocean environment. Based on the numerical results, the effects of various structure parameters including the taper angle, the height and thickness of the tower, the depth, and the diameter and the cement filler of the monopile on the fundamental natural frequency of the wind turbine tower system are investigated in detail. It is found that the fundamental natural frequency decreases with the increase in the taper angle and the height and thickness of the tower, and increases with the increase in the diameter of the monopile.

# Dynamic performance analysis for wind turbine in complex conditions. This article presents a method to get dynamic responses of a wind turbine under different conditions. The time-varying load acting on the blade is calculated by using the blade element momentum theory, and the dynamic performance of the wind turbine are calculated by applying the modal superposition method with blade loads as excitations. The dynamic response process is adopted to carry out a dynamic analysis, and theoretical results are compared with experimental results, indicated that the analysis presented in this paper is correct. The results indicate that the wind turbine experiences a huge transverse vibration under turbulent wind, the hub vibration is intensified up to 179.52 %, and the vibration of the blade tip intensifies up to 190.41 % under the action of gusts in extreme conditions relative to the steady state, which shall be considered during design. * This article presents a computing method to get dynamic responses of a wind turbine under different conditions.
