We provide engineering services for automotive: structural analysis and multiphysics modelling.
FEM simulations provide an in-depth understanding of the complex relationships between individual design parameters. This allows to improve efficiency and durability of devices, decrease costs and reduce design time. Calculations can be perfomed as linear or non-linear taking into account contacts and plastisity.
STRENGTH - DYNAMICS (FEM)
Dynamic simulations allow simulations with large deformations, e.g., vehicle collision with an obstacle. We have extensive experience in pedestrian safety modeling, where the response of vehicle equipment (e.g. wipers) to a pedestrian impact is checked to minimize injuries resulting from such an event.
We simulate production processes and other nonlinear problems (e.g. transmissions gears).
Fatigue cracks can result from stress concentrations and the presence of internal defects. We perform crack propagation calculations on the basis of Paris's law and the integral J as the fracture parameter.
THERMIC AND COUPLED SIMULATIONS
An extremely important aspect in the automotive and railway industries are thermal simulations coupled with fluid flow (gases and liquids). The thermal state of the device affects operating parameters of its components (cooling) and thermal stresses.
Coupled thermal and flow simulations are also used to determine passenger comfort and optimize ventilation and air conditioning systems.
Aerodynamics affects the vehicles stability and drag, which directly translates into fuel consumption. The aerodynamic forces can lead to a loss of control and lead to an accident.
In case of trains the aerodynamic analysis covers such events like impact of the train induced wind on the near track equipment and passing through tunnels. Aerodynamic simulations can predict problems at design stage and give opportunity to introduce appropriate modifications in advance.
In the automotive industry, in addition to aerodynamics and internal flows, simulation methods are also used to predict soiling and the effects of driving in rain (rain water management).
