Experimental Evaluation of the Lever Arm Coefficient when Rolling an Aluminum Alloy Strip
An analysis of power parameters of aluminum alloy sheet rolling determined on the base of the data collected in the dynamics of operation of the production monitoring system has been made. Using analytical equations, the lever arm coefficient of the rolling force resultant was calculated. The average statistical coefficient of 0.48 was determined within the area of quasi-monotonic deformation as much as 29 %. Applicable scope of results: sheet rolling of aluminum alloys. The obtained characteristic curves allowed us to draw conclusions about the presence of stationary and non-stationary periods of changes in the resultant force coefficient.
