| 摘 要： | In this paper, natural frequencies and vibration modes of spindl D1203 are calculated by us-ing structural analysis program SAP84. It is found that the second natural frequency of D1203spindle is too close to the range of working speed. In order to raise the second natural frequencyand to reduce the vibration noise, simple optimal design of several structural parameters are alsodiscussed by means of the orthogonal design method. It is shown that the better design is toshorten the length of the spindle blade appropriately and to increase the elasticity of its uppersupport.

| Abstract: | In this paper, natural frequencies and vibration modes of spindl D1203 are calculated by us- ing structural analysis program SAP84. It is found that the second natural frequency of D1203 spindle is too close to the range of working speed. In order to raise the second natural frequency and to reduce the vibration noise, simple optimal design of several structural parameters are also discussed by means of the orthogonal design method. It is shown that the better design is to shorten the length of the spindle blade appropriately and to increase the elasticity of its upper support. |
