In the theoretical models, a film splitting model using a power-law type equation, a roll gap model based on elasto-hydrodynamics and a flow model from a rotating cylinder system were applied. The parametric computations to each operation condition revealed the steady and dynamic behaviors of a coating film and liquid films on coating rolls. From the results of the frequency response to the speed disturbances of the coating rolls, it was found that the sensitivity of the lowest coating roll to the disturbance was a half of others, which implies that the requirement for the accuracy of a driving system for the coating roll is not so severe compared with others. The experimental data and the numerical results at steady state agreed in large part. The actual properties of materials used in the coating process will be required to predict the coating thickness precisely. © 2011 The Japan Society of Mechanical Engineers., 金沢大学先端科学・社会共創推進機構}, pages = {1335--1349}, title = {4本ロールコーティングシステムの数値解析に関する研究}, volume = {77}, year = {2011} }
