摘　　要：以实际工程中常用的2种叶片形式调节挡板为例,采用有限元软件进行三维建模分析。通过流场分析,对比2种挡板的阻力特性和调节性能;通过力学分析,对比2种挡板的应力和形变。结果表明:平板型叶片挡板比流线型叶片挡板的调节性能更好,流线型叶片挡板比平板型叶片挡板的力学性能更好。Taking two commonly used blades types of adjustment baffles in practical engineering as research examples,analyses with 3D modelling were conducted by applying finite element software.Comparisons were carried out between the resistance characteristics and adjustment performance of two types of adjustment baffles through flow field analysis;meanwhile,comparisons were carried out between the stresses and deformations of two types of adjustment baffles through mechanical property analysis.Results show that,the flat plate blade baffle has better adjustment performance than the streamlined blade baffle,while the streamlined blade baffle has better mechanical property performance than the flat plate blade baffle.
