摘要
本文利用ANSYS Workbench软件中的Static-Structural模块对现代化的某型号风电机组的高速制动器壳体进行了应力分析。分析结果显示:高速制动器在制动过程中,其上壳体的最大应力大于其壳体材料的屈服强度,这极易造成上壳体结构的变形,而通过增加半径为1 mm的圆角进行过渡,使上壳体的应力大幅减小,最大应力低于其壳体材料的屈服强度。该研究结果可为现代化的某型号风电机组高速制动器壳体的优化设计提供可行性方案。
This paper uses the Static-Structural module in the ANSYS Workbench software to carry out a stress analysis on the high speed brake shell of a modern type of wind turbine.The analysis results show that the maximum stress of upper shell is greater than the yield strength of its shell material during the braking process of the high speed brake,which can easily cause deformation of upper shell structure.By increasing the fillet with a radius of 1 mm for transition,the stress of the upper shell is greatly reduced,and the maximum stress is lower than the yield strength of its shell material.The research results can provide a feasible scheme for the optimization design of high speed brake shell of a modern type of wind turbine.
