NUMERICAL SIMULATION OF STRESS, DEFORMATIONS, FLOW AND TEMPERATURE FIELEDS

An example of the transport system developed and manufactured at VUTS can be a transport table determined to the fast transporting of plastic pallets.

 

NUMERICAL SIMULATION OF STRESS, DEFORMATIONS, FLOW AND TEMPERATURE FIELEDS

Methods of numerical simulation of temperature and flow fields are used for the VERIFICATION OF NEW HYPOTHESES still in the pre-production phase by describing the existing solution to FIND THE CAUSE OF MALFUNCTION and to design an IMPROVEMENT



COMPUTATIONAL MECHANICS OF SOLIDS

Modern numerical simulations enable to make the process of designing the machine parts and units more effective. Optimization of mechanisms, simulation of their behaviour, possibly other up-to-date procedures lead to the gradual reduction of energy demands of machines, reduction of environmental loads and increase of their productivity.

Professional activities of the department Computations and Modelling are focused on solving research and development tasks and projects in the area of the mechanics of solids in the following fields:

  • Research in the area of computations and mathematical modelling of physical processes
  • Analysis, optimization and development of designs by the method of finite elements (FEM)
  • Assessment of deformations, stiffness and stress of machine components and units
  • Static issues
  • Dynamic issues – natural frequency and shapes, excited oscillations
  • Non-linear tasks, i.e. models of materials with a non-linear behaviour at mechanical stressing and their verification on the basis of the experiments carried out, contact tasks, large deformations
  • Simulations and optimizations of mechanisms
  • Evaluation of reactions and dynamic effects
  • Research of new materials
  • Modelling and experimental research of composite materials
  • Substitution of metal components of the machines with ecologically and economically favourable composite components
  • In order to solve these tasks the department is equipped with the following software:

SW – I-DEAS, NX 7, MSC.MARC, NASTRAN, MSC.ADAMS

 

COMPUTATIONAL MECHANICS OF LIQUIDS

 

Mathematical modelling of physical processes in the area of liquid mechanics enables to inspect the problem itself, especially, in the cases where it is not technically possible to carry out measurements, or the manufacture of a prototype would be too expensive. At the same time it enables to effectively understand the issue and makes the subsequent process of a new equipment design easier. Currently the simulations of flow reach a high level of being closer to the real process and they have a close relationship to the applications in the technical practice.

Other activities of the department Computations and Modelling are oriented on solving the research and development tasks and projects in the area of liquid mechanics with the application of numerical simulations of flow:

Numerical simulations of complex flow fields

Computations of compressible viscous flow

Laminar and turbulent flow in a large range of speeds

Mathematical simulations of flow with the heat transfer and processes of burning

Multi-phase liquid flow and solid fraction drifting by flow

Numerical simulations of permeability of composite layers

Development and optimization of design solutions in terms of liquid impacts

Computations of force effects of gases and liquids and their interaction with the surroundings

The solutions of tasks are implemented on the latest computer systems by means of the software Ansys Fluent®
