Simulations

Structural simulations

The simulation of the product functionality is the most cost and time effective method of product validation, because it can be done in the early development stages. It allows us to provide an accurate insight into the operation of the product and thus detect potential design errors long before the availability of prototype products and testing devices.

We have over 10 years of experience with simulations according to automotive industry standards and in that time have implemented over 300 simulations of different types and complexity:

• non-linear mechanical simulation of complex assemblies (pedal assemblies, accessories, parking brakes, flywheels, vehicle suspensions, brake discs, etc.),
• crash simulations,
• thermal and thermo-mechanical simulations (brake discs, drums, flywheels, etc.),
• fatigue,
• modal analysis,
• simulations of polymeric products with fiber orientation,
• simulations of rubber parts.

Structural simulations are carried out in the Abaqus software, a leading simulation program based on the finite element method.

Sheet metal forming simulations

Simulations of sheet metal forming are carried out in the Abaqus software, which enables a detailed analysis of contact conditions in the forming tool (taking into account selective lubrication, foil, etc.) and a wide range of material constitutive models (anisotropic behavior, degradation of the elastic moduli, FLD, other material damage mechanisms, etc.)

A great deal of attention is given to a detailed characterization of material properties. This is a key step to achieving accurate simulation results. In agreement with the customer, we can also provide a test of the material and production of samples.

You can send us a 3D model of tool functional surfaces or just a 3D model of the product – in this case we determine the steps of sheet metal forming and design the functional surfaces of the tool.

Injection molding simulations

The simulation of plastic injection molding is carried out in the Moldex software, which allows a detailed analysis of contact conditions in the tool, and includes a wide range of material models with sufficient material data library.

A great deal of attention is given to a detailed characterization of material properties. This is a key step in achieving accurate simulation results. In agreement with the customer we can also provide a test of material.

You can send us a 3D model of the tool cavities with the product or just a 3D model of the product – in this case we determine the position of molding inlets and cooling channels.

CFD simulations

CFD simulations are performed in the OpenFoam software. We carry out calculations of air resistance and analysis of natural and forced convection (electronic components, brake discs, etc.). Send us an inquiry by using the form on our Contact page or sending us an e-mail to info@cafuta.eu.
