机架刚性对织机性能参数的影响

Influence of frame rigidity on loom performance parameter

通过对组成机架的撑档不同截面条件下的试验,认为提高撑档的静刚度可以提高机架的整体刚性,并可消除因机架刚性不足对整机各项性能指标造成的影响。当机架的刚性接近刚体时,进—步提高机架刚性,则不能明显改变整机的性能指标。撑档截面形状的变化对撑档的抗变形能力有较大的影响,在考虑机器结构合理,满足要求的条件下,通过撑挡截面形状的选择,可以提高机架的刚性。

Through tests for all the sections of the support frames under various section conditions, it was resulted that the whole rigidity can be improved by increasing the static rigidity of the frame and consequently the effect to the performance of the whole machinery can be eliminated due to insufficient rigidity of the frame. When the frame rigidity approached to the rigid body, the performance of machinery would not be obviously improved even if the frame rigidity would be further increased. The shapes changes of the frame sections have remarkable effect on the anti-deformation of the frame. Therefore, frame rigidity can be improved through selection of shapes the frame sections after machinery constructions were seasonable and satisfied the requirements.
