| 摘 要： | 本文运用 SAP84结构有限元通用程序计算了国产 D1203型锭子的前四阶固有频率及振型,解出该锭子的第二固有频率接近于工作速度区,并运用正交设计方法对锭子的几个结构参数进行了初步优化设计,指出欲提高锭子第二阶固有频率,降低噪声,可采取适当缩短锭杆长度,增加上支承弹性的方法。

| Abstract: | In this paper,natural frequencies and modes of spindle D1203 have beencalculated by using structural analysis program SAP84.By means of calculationsit was found out that the second natural frequency of D1203 spindle is too closedto the region of wotking speed.In order to raise the second natural frequencyand to reduce the noise,simple optimal design of several parameters also have beendiscussed by means of the method of orthogonal design.From the discussion itwas known that the better design is to short properly the length of blade andincrease the elasticity of upper support. |
