Digital simulation is a way of analyzing the behavior of a proposed design by using CAE tools. The use of CAE tools has enabled the automotive industry to reduce product development cost and time while improving the safety, comfort and durability of the vehicles.
Digital simulation methods allow engineers to:
The starting point for digital simulation is always a digital 3D model of a concept. Based on this model a specific simulation model is developed in pre-processor software where geometry is cleaned and meshed with elements. On top of the geometrical data the material properties, joints, joining methods, loads etc. are needed to be able to complete the simulation model in pre-processor.
The general steps for digital simulation are:
This cycle is iterated, often many times, for optimizing the design. Modern software can automate certain iteration processes to achieve pre-set targets.
