Finite element analysis

FINITE ELEMENT ANALYSIS

  • Investmech uses:

  • MSC suite of finite element analysis packages
  • Prokon (for finite beam element analysis on structures).

Finite element modelling and analysis is used as a tool in design and structural integrity assessment projects. However, it is also offered as a standalone service to our clients where the client provides Investmech with models and structural inputs.

Transient finite element modelling

Investmech has vast experience in transient finite element modelling and analysis:

  1. Crash simulations between vehicles
  2. Thermal and structural coupling in heat transfer calculations for furnace and ladle design
  3. Liquid and structural coupled modelling to design lids for liquid metal transport ladles
  4. Towing devices
  5. Heat exchangers

Finite element analysis of LHD load box

Mission profile driven finite element analysis based structural integrity assessment of an LHD load box

Finite element analysis of furnaces, ladles, refractory

Investmech has vast experience in the accurate modelling and simulation of transient (and steady-state) furnace or ladle thermal and structural responses. Applying international accepted material compliance criteria designs are produced that complies with user requirements.  State-of-the-art analysis software is pushed to the limit to model refractory bricks in contact with each other.

Application of finite element analysis in problem solving and design

Typical work that are performed:

  • Solve resonance in structures and automotive vehicles
  • Design hoisting systems and elevated platforms
  • Determine temperature distributions
  • Using finite element analysis as part of a virtual product development strategy allows Investmech to introduce new products into the market faster and at reduced cost.  This reduced the amount of prototypes needed whilst introducing a broad scope for optimisation.
  • Solve engineering problems
  • Design new components
  • Audit designs and do modifications to ensure compliance with international standards and mission profiles

Finite element modelling of fluids in containers – sloshing

Slosh and sloshing of liquid aluminium during impact was calculated to find crash dependent forces on the lid of a liquid metal ladle.  These forces were used to design sufficient clamps and stiffening of the lid to prevent leakage during potential accidents.
