动压轴承锭子临界转速及振型的计算分析

Calculation and analysis of critical speeds and mode shaps for textical spindle with special oil-film bearing

采用传递矩阵法及导纳法编制了计算程序 ,分别对锭子在空锭、带筒管但筒管上无纱线、带筒管且筒管上带满卷纱线三种状态下的第一阶、二阶临界转速和振型进行了分析计算。文中给出了计算结果 ,经试验验证 :计算结果和试验结果相一致 。

In this paper, based on the matrix method and mobility method, the computer program was established and the critical speeds, mode shapes of spindle under three operation conditions (no bobbin, with bobbin but no cotton yarn on the bobbin, and full mass of cotton yarn on the bobbin ) were calculated by our computer program, the calculation results are given. The calculation results coincide with the test results so it verified that the calculation method and computer program in this paper are effective.
