PC Ulyanovsk NIAT has applied engineering analysis for more than 10 years for development of new process and flow diagrams for both research and applied tasks. During this period, an extensive experience of engineering analysis application has been accumulated both in the scope of metal working process and in other spheres.

The LS-DYNA license program is used as the main program for engineering analysis at PC Ulyanovsk NIAT. The program is used for analyzing various dynamic processes being one of the best for metalworking processes simulation.

 PC Ulyanovsk NIAT lyanovsk NIAT carries out research studies.

Product forming according to Incremental Sheet Forming (ISF) Method that comprises a series of low-level deformations by means of an end-piece secured in a robotic arm (CNC), can be attributed to such studies. Application of such method allows producing both rectangular and conical products from different materials, including composites. Simulation allows revealing parts manufacturing process flow patterns by means of ISF Method.

Simulation of cutting processes allows to acquire data relating both to treatment process flow pattern (it can be applied to the processes of sheet material blanking, e.g., sections cutting), and to machining as well (drilling and milling processes). Different methods available in LS-DYNA Program have been used for cutting processes simulation: Lagrange method, smoothed particle hydrodynamics (SPH) method, Galerkin's method (EFG), etc.

The analysis of processes of sections cutting allows determining the optimum shape of cutting knife providing for minimal section edge distortion and minimal cutting force.

Some directions of engineering analysis conducted at PC Ulyanovsk NIAT are associated with investigation of peeling or segregation of material layers processes. One of the basic research directions is the investigation of processes of coated material deformation, where damaged coating appears as a result of tool effect on the material, which brings about a reduction of protective and decorative material properties.

Cold and hot forging being a challenging subject for engineering analysis, is one of the key directions of metal working process (MWP). The simulation allows finding optimum shapes of jigging (values of pattern draft angles, radii of rounding, etc.) as well as parameters of blank and tool materials providing for flawless manufacturing process. 

Application of engineering analysis means, namely, LS-DYNA Program, allows building simulation for various dynamic processes with great accuracy: MWP, machining, etc., which allows visualization the process as if it took place during practical testing. The simulation allows acquiring all necessary data with respect to the stress and strain state and processing power parameters. In case of defects detection at the blank or tool, the simulation allows detecting the above defects even at the stage of product designing.

All these factors allow removing all defects at the stage of designing and developing a highly-efficient and advanced scheme with minimal losses in the course of production launching.
