纺纱锭子临界转速的优化设置

Optimal Placement of Critical Speeds in Ring Spinning Spindle

先对纺纱锭子的动力特性作敏度分析，合理选择设计变量，再进行临界转速优化设置的送代计算，可使设计的纺纱锭子在工作转速区内有较小的振动和功耗。

First a set of sensitivity coefficients in dynamics is calculated, then an iterative processof the optimal placement of critical speeds in a ring spinning spindle is operated on the basis ofreasonable choice of design variables. The design objective is the minimization of the responseamplitude of the ring spinning spindle within it's operation range.
