CAE Simulation

By using finite element analysis, we can develop products in a much more efficient way, with the resulting reduction in time and costs. Likewise, computer-aided engineering (CAE) ensures that the products designed comply with all of the client’s requirements.

For this reason, Btechc has a calculation department made up of specialised engineers to provide support in the product development process, as well as carrying out specific calculation projects.

Technical capacities

  • Stiffness studies
  • Durability and reliability studies
  • Structural design optimised for impact
  • Pedestrian protection
  • Low-speed impacts
  • Thermal expansion studies

Specialisation:

Front-end module

The front-end module supports pieces that are essential to the proper working of the vehicle. The headlamps, radiator and bonnet clasp are just a few examples. Therefore, manufacturers require guarantees that the front-end meets their stiffness requirements (both static and dynamic) and properly protects pedestrians.

  • Static requirements
  • Dynamic requirements
  • Hybrid technology

Bumper

 

Body

 

Moving parts

The design for the moving parts of a vehicle must take into account the need for a light structure for operability and stiffness for functionality. Plus, in the case of the bonnet it must collapse properly in a high-speed impact.

  • Bonnet: simulation of tests affecting this component:
    • Torsional stiffness
    • Flexural stiffness
    • Indentation tests
    • Modal analysis
    • Bonnet drop
    • Pedestrian head impact
  • Doors: developing this components based on the following tests:
    • Door drop
    • Over-opening
    • Frame stiffness
    • Girdle stiffness
  • Bonnet lid: simulation of tests affecting this component:
    • Torsional stiffness
    • Flexural stiffness
    • Modal analysis
    • Lid drop

Coaches and buses

The body of a coach or bus must withstand the maximum accelerations that occur in driving conditions. The structural calculation requires a detailed distribution of mass to reproduce the tensional state of the vehicle. Additionally, regulation R-66 requires safety rings to be designed in the superstructure to ensure there is a survival space if the vehicle rolls over.

  • Body: semi-static simulation applying acceleration fields:
    • Curves
    • Sharp breaking
    • Evaluation of load buckling and roof endurance
  • In accordance with the provisions of regulation ECE R-66, we create models with all of the inertia characteristics to be used in dynamic calculations:
    • Dynamic rollover simulation in accordance with ECE R-66
    • Design for safety rings
    • Design for connecting structures
  • Designing and calculating equipment mounts and durability analysis with signal spectrums registered en route.

Virtual laboratory:

For companies that develop their own products but don’t have the resources to carry out their own calculations, we act as a virtual laboratory. From a list of calculation requirements:

  • We simulate behaviour
  • We optimise it or suggest improvements
  • We record the results
