Simulation study on de-icing of wind turbine blades based on ultrasonic micro-vibration
摘要
Abstract
Although the airfoil of wind turbine blades is curved,when piezoelectric elements are arranged at local positions for de-icing,it can be approximately regarded as a flat plate.Based on this,this paper conducts a simulation study on de-icing of flat plates using ultrasonic micro-vibration.Firstly,modal analysis of the flat plate is performed using Ansys Workbench to identify the optimal de-icing modal vibration mode and the placement of piezoelectric elements.Then,based on the modal analysis,a harmonic response analysis is conducted to investigate the influence of two types of piezoelectric ceramics,PZT-4 and PZT-5,on the maximum shear stress at the ice adhesion interface.Finally,using the de-icing area ratio as an indicator,the effects of the thickness,shape,number,and spacing of piezoelectric elements on the de-icing effect are quantitatively analyzed.The simulation results show that under the optimal conditions of piezoelectric element thickness,shape,number,and spacing,the system's de-icing area ratios are 78.44%,78.13%,87.41%and 86.73%,respectively.This paper can provide theoretical references for the design of de-icing systems.关键词
