摘要
针对叶片泵的各种类型叶片受力特性不同的问题,以无厚叶片、顶部为圆弧的单面后倾叶片及对中圆弧叶片三种类型为例,对吸油区的叶片受力进行分析建模,仿真得到一系列叶片所受接触反力的变化曲线。结果表明:忽略叶片厚度得到的结果与实际情况有很大的差异,顶部有圆弧的叶片比单面后倾叶片受力状况要好。
Aimed at the problem that dynamic characteristics is different to all kinds of vane in vane pumps,a dynamic force model is established for three types of vane i.e.thick-less vane,circular single-side backward vane and vane with circular skeleton line,and then a series of variation curves of contacting reactional force are obtained by simulation.The results show that there will be many differences if the vane's thickness is ignored,the force's action of the vane with arc top is better than single-side backward vane. The conclusions of the paper will provide helpful reference for studying and designing a high-pressure vane pump with high performance.
