چکیده

temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. in this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. one of the basic parameters of strip rolling processes is temper rolling force. a new rolling force model has been proposed for temper rolling strip mill considering the inhomogeneous stress distribution along the thickness of the strip. the contact between rolls and thick strip is totally elastic. the deformation field consists of an elastic (actually elastic) zone and that is highly non-homogeneous across the thickness of the strip. totally elastic formulation can be used to predict the roll force. it can be used to study the stress distribution along the thickness of strip. the computing results from this model coincide the similar presented results in previous investigations done.

a new rolling pressure model for an actual reversing cold rolling strip mill

the forging model for cold rolling is one of rolling models that is used in rolling calculations. in this model,the final rolling pressure is an average value and it is not an accurate model.also by using this model,the firction hill curves are plotted due to the central point of the rolling bite length while frictional stresses intersect at the neutral point.in this study, a new model based on...

Design, Modeling, and Construction of a New Tactile Sensor for Measuring Contact-Force

This paper presents the design, modeling, and testing of a flexible tactile sensor and its applications. This sensor is made of polymer materials and can detect the 2D surface texture image and contact-force estimation. The sensing mechanism is based on the novel contact deflection effect of a membrane. We measure the deflection of the membrane with measuring the strain in the membrane with emb...

A new solution method for wheel/rail rolling contact

To solve the problem of wheel/rail rolling contact of nonlinear steady-state curving, a three-dimensional transient finite element (FE) model is developed by the explicit software ANSYS/LS-DYNA. To improve the solving speed and efficiency, an explicit-explicit order solution method is put forward based on analysis of the features of implicit and explicit algorithm. The solution method was first...
