摘　　要：以茶叶揉捻机的揉盘为研究对象,分别通过有限元分析软件和动态测试得到茶叶揉捻机揉盘的主要低阶模态。通过对比有限元分析和动态测试的结果,发现茶叶揉捻机的揉盘在低阶存在一定的动态缺陷。针对揉盘低阶时存在动态性能的缺陷,通过改进环型支架的尺寸数值,提升茶叶揉捻机揉盘的动态特性。当揉盘直径为210mm时,若采用环型支架,环型支架的外径大小在25mm左右能保证揉盘的动态性能,为进一步的提高茶叶揉捻作业的水平具有重要的现实意义。This paper takes the tea kneading machine kneading disc as the research object,respectively,the main low order mode kneading disc tea twisting machine is obtained by finite element analysis software and the dynamic testing.By comparing the finite element analysis and the dynamic test results,found a tea kneading machine kneading disc in low order dynamic existence some defects.Aiming at the existing defect kneading disk dynamic performance of low order,through numerical improved ring stent size,improve the dynamic characteristics of the kneading tray of tea rolling machine.When kneading disc diameter is 210 mm,if the ring bracket,the outer diameter of annular bracket can guarantee the dynamic performance of kneading disc at about 25 mm,has important practical significance for further improving the tea kneading operation level.
