均匀轧辊压力配伍模型设计
|
摘要
为提高织物轧压后的轴向轧液均匀性,减少左中右色差,首先论述均匀轧辊内部结构与工作原理,分析轧液均匀性影响因素,然后利用ANSYS/LS-DYNA非线性动力分析软件,对均匀轧辊辊系有限元模型进行数值模拟,分析辊腔油压大小对辊间压力分布的影响,在轧车承载范围内设计多组压力方案,建立均匀轧辊有效幅宽范围内气囊气压与辊腔油压的配伍模型,最后进行了轧压实验。结果表明:按照经验取油压载荷时,沿辊身轴线方向平均轧余率差值为7.3%;按照压力配伍模型取油压载荷后,轴向最大轧余率差值均小于5%,平均轧余率差值为3.1%,满足生产中对轧液轴向均匀性的要求。
In order to improve the uniform distribution of rolling fluid, and reduce the color differences along the roll width, internal structures and working principle of the evenness rollers were described firstly. The factors affecting the uniformity of the rolling liquid were analyzed. A finite element analysis model of evenness rolls was built with ANSYS/LS-DYNA software. Numerical simulations of the finite element model of roll system were carried out. Pressure distributions between the evenness rolls were analyzed. And then, several pressure schemes were designed within the bearing range of the rolling machine. A matching model between air and oil pressures of evenness rolls was established. Finally, experiments were carried out to compare the differences when air and oil pressures were taken according to matching values and empirical values, respectively. The results show that the average residual ratio is 7.3% when the empirical oil pressures are taken, while the maximum residual ratio is lower than 5% and the average residual ratio is 3.1% when the oil pressures are taken according to the air-and-oil matching model, which meets the requirement of the axial uniformity in the production.
