某燃气轮机压气机可转导叶流固耦合数值研究
|
摘要
为了准确得到某燃气轮机压气机可转导叶的驱动力和动静间隙,校核可转导叶的强度,笔者利用ANSYS Workbench平台在压气机的堵塞工况下对可转导叶进行了流固耦合分析。提取了各工况下导叶的应力、变形和气动阻力矩,校核了可转导叶的强度,为动静间隙的选择、驱动力计算和驱动机构的选型提供了依据。
In order to accurately obtain driving force and dynamic and static interval of rotatable guide vane of compressor of gas turbine and check intensity of rotatable guide vane, the authors conducted fluid-structure interaction to rotatable guide vane by using ANSYS Workbench platform under condition of compressor blocking. Then, the authors extracted stress, deformation and pneumatic drag torque of guide vane under all working conditions, and checked intensity of rotatable guide vane,which provided references for selection of dynamic and static interval, calculation of driving force and model selection of driving mechanisms.
