Method and apparatus for determining rolling force in flat roller rolling process of corrugated composite plate

A method for determining a rolling force in a flat roller rolling process of a corrugated composite plate, comprising:

• determining second rolling parameters in the flat roller rolling process;
• wherein the second rolling parameters comprise a rolling reduction, a contact arc length, and a shear yield stress parameter, and the second rolling parameters are calculated from a first rolling parameters of the flat roller rolling process of the corrugated composite plate;
• the first rolling parameters comprise a cladding metal layer thickness of the corrugated composite plate, a base metal layer thickness of the corrugated composite plate, a width of the corrugated composite plate, a roller radius, a contact friction coefficient between the cladding metal layer and an upper roller, a contact friction coefficient between the base metal layer and the lower roller, a front entry tension, a post-entry tension, a cladding metal layer thickness and a base metal layer thickness of a flat composite plate after rolling, a quantity of corrugations on the corrugated roller, a corrugation amplitude and an equivalent radius of the corrugated roller;
• partitioning a first state deformation zone based on a first neutral point to obtain a first zone set, and determining a first total rolling force based on the first rolling parameters, the second rolling parameters and the first zone set;
• wherein the first state deformation zone is a rolling deformation zone where the upper roller is fully in contacted with the upper surface of the corrugated composite plate;
• partitioning a second state deformation zone based on a second neutral point to obtain a second zone set, and determining a second total rolling force based on the first rolling parameters, the second rolling parameters and the second zone set;
• wherein the second state deformation zone is a rolling deformation zone where an upper roller is partially in contact with the upper surface of the corrugated composite plate;
• and
• determining a target rolling force in the flat roller rolling process based on the first total rolling force and the second total rolling force.
