摘要
含有大量柔性零部件的多级可调静子叶片是压气机的重要防喘措施,柔性零部件的弹性变形会对可调静子叶片的调节精度和调节角度一致性产生较大影响。以高压压气机多级可调静子叶片为研究对象,使用ADAMS虚拟样机仿真软件对其进行刚柔混合动力学仿真,并对仿真结果进行分析,验证了多级可调静子叶片设计的合理性。改变联动环支架的间隙和数量进行仿真,并对结果进行分析,得到了联动环支架与机匣之间的径向间隙以及联动环支架数量对静子叶片调节精度的影响规律。研究表明:联动环支架数量为8个,且支架间隙在0.05~0.10 mm之间,调节机构的调节精度最高。
Multi-stage adjustable stator vane is an important anti-surge measure for compressor,which contains a large number of flexible parts.The elastic deformation of flexible parts has great influence on the adjusting precision and angle consistency of adjustable stator blades.The multi-stage adjustable stator vanes of a high-pressure compressor were taken as the research object,and the rigid and flexible mixed dynamics simulation was carried out by using ADAMS virtual prototype simulation software.The simulation results were analyzed to verify the rationality of the design of multi-stage adjustable static vanes.Different simulation data were obtained by changing the clearance and the number of the linkage ring bracket.By analyzing different simulation data,the influence rule of radial clearance and number between the linkage ring bracket and the casing on the regulation precision of stator vanes was obtained.The research results show that the optimum number of linkage ring supports is 8,and the clearance of the supports is between 0.05 mm and 0.10 mm,and the adjustment precision of the adjusting mechanism is the highest.
