Description
Technical field
The present invention relates to plate forming fields, more particularly to a kind of three roller edge rollings to be molded method of numerical simulation.
Background technology
At present when being molded to plank, plank can be molded using furling plate round machine, but be rolled up to plank
When circle research, numerical value when needing to be molded edge rolling carries out analog study, is carrying out analog study to edge rolling molding numerical value at present
When, the research method of complete set, can not only study, it is easy to cause research side according to the working experience of technical staff
To deviation is generated, cause research that mistake occurs.Therefore, designing one kind three roller edge rollings molding method of numerical simulation just seems outstanding
It is important.
Invention content
In view of the deficiencies of the prior art, the object of the present invention is to provide a kind of three roller edge rollings to be molded numerical simulation study side
Method, by system to edge rolling be molded numerical value simulate, so as to get numerical value it is more accurate, convenient for plank edge rolling when it is each
Item numerical value carries out sunykatuib analysis, convenient further to be studied edge rolling work.
The present invention provides a kind of three roller edge rollings molding method of numerical simulation, and steps are as follows for the research method：
Step 1：According to the technical parameter of squeezer, the roller of model and the geometric dimension of strip are determined；
Step 2：According to the stressing conditions in forming process, while reducing and calculating the time, selects two-dimensional model modeling；
Step 3：It selects three forming rollers to parse rigid body, and carries out analysis step and boundary condition determination；
Step 4：Each surface definition contact pair of molding roller, steel plate, locating back, according to setting releasing pair in ABAQUS
During requirement about master-slave contact surface, set rigid body surface as interarea, steel plate upper and lower surface is from face；
Step 5：The contact surface of locating back and steel plate is set as interarea, the upper and lower surface of steel plate is from face；
Step 6：Carry out the selection of cell type and the division of network；
Step 7：It obtains simulation result and analyzes it.
Further improvement lies in that：Simulation process during analysis step and boundary condition determine in the step 3 is divided into three steppings
Row：The forming roller of selection is carried out number consecutively, and carries out number consecutively to axis by the first step；Second step, No. 1 roller of display, No. 3
Translation of the roller along 1,2,3 directions and the rotation around 1 axis and 2 axis move up No. 2 rollers；Third walks, and No. 3 rollers are moved up along 2 axis directions；
4th step gives plank feed speed along 1 axis forward direction, completes simulation process.
Further improvement lies in that：In the step 6 carry out cell type selection and network division when, due to plank
Thickness it is much smaller compared to length and width, therefore regard it as shell, the cell type of plank selects four nodes reduction integral shell
Unit.
Further improvement lies in that：Since reduction integral unit has " hourglass " that tessellated mesh is used in the step 6
To alleviate hourglass problem, the judgement for hourglass problem is judged by checking the ratio between pseudo- strain energy and interior energy.
The beneficial effects of the invention are as follows：By system to edge rolling be molded numerical value simulate, so as to get numerical value more
Accurately, every numerical value when being convenient for plank edge rolling carries out sunykatuib analysis, convenient further to be studied edge rolling work, and
By mathematical computations, every data materialization when by plank edge rolling so that can be more accurate fine in further research
Carry out process improving.
