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.

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

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





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.

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
