Emulation and virtual commissioning promise benefits over the classical approach, not only when used for lower level controls (e.g. PLC codes), but also for higher level controls such as material flow controls.
The information inputs are broadly of two kinds: product information describing the material flow; and control information defining the characteristics of this material flow and the operations taking place on the material flow.
Referencing the simulation results and the principal guidelines, the geometric shape of the drawbead is adjusted partly, and the material flow is controlled effectively during the drawing process.
The company was experiencing problems in scheduling and plant layout leading to further problems in materials flow, labour control, inventory and purchasing, material handling system, and production space.
Conditional logic based controllers that control the material flow rate into the reactor and to control the H2 fed to the burner were developed and implemented in drive cycle simulations.
The approach includes (re- planning of the automated matere- planningstem, cofmissioning ithelogic control automatedolling the material flow.
Novel billet design using a shortened core was explored in an effort to control material flow during the co-extrusion of plain carbon/stainless steel tubes.
The mechanism is realized by implementation of a sliding insert in die structure to control material flow and further to avoid the formation of folding defect.
And a DDF system with multi-point blankholder control system was developed to control the material flow, thereby to prevent sheet parts from wrinkling and tearing.
Applications of the model arise in metallurgical materials processing, chemical engineering flow control, geothermal hydromagnetics, etc.
