Joint Stock Company Ulyanovsky NIAT brings to your notice the fulfillment of various types of simulation through LS-DYNA software. The company permanently carries out different scientific researches with implementation of ANSYS/LS-DYNA mathematical simulation software. These explorations are directed to studying of metalworking deforming processes, massive and sheet-forming operations, blows, crash-tests, thermal phenomena, destruction, rollforming and also many other processes.

The mathematical simulation software of LS-DYNA allows exploring the most different processes and phenomena:
computer aided designMetalworking deforming processes of a (bulk, sheet forming operations);
Crash AnalysisBlow processes and crash-tests;
design engineeringThermal phenomena;
ls-dynaDestruction and explosion processes;
finite element analysisAcoustics processes;

We provide:

crash analysissimulation of any METALWORKING DEFORMING: bulk, massive forming operations, forging, coining, precision stamping, metal powder stamping, upsetting, rolling, tube and ring rolling, tube reducing, extrusion, drawing, ironing, co-extrusion and co-drawing, cogging, stretching, cutting, punching, sheet forming and roll forming processes by virtue of mathematical methods;
DYNABlow, percussion and intrusion processes, crash-tests, etc. simulation;
Computational DynamicsDynamic and fast flowing processes simulation by the numerical methods.

Our researches allow determining:

crash test Computer Aided Engineering Tense deformed state both in explored and blowing (forming) parts at any point of a model and within any time interval;

services, industry Critical, dangerous segments of a model where destruction or structural deformation is possible;

finite element model Force, energy, deforming, contact magnitudes in course of model components interworking. Dynamic

Our explorations allow fitting:

ANSYSOptimal metalworking deforming and other technological processes;
