abstract = {Computer Aided Engineering techniques (CAE) are extensively
used for designing car body structures. However, their
success depends on the accuracy of input data used in the
analysis. This poses restrictions on their use in concept
design phase of the car body, as the accuracy and
availability of input data is limited during this phase.
This thesis develops a knowledge-based design approach to
address these challenges. It also demonstrates the
application of this approach for conceptual design of a
profile based car body structure designed for
crashworthiness.The knowledgebase for the presented design
approach is developed by analysing the results from two sets
of numerical experiments carried out during this work. The
first set of finite element (FE) simulations is performed on
two benchmark vehicles constructed using the classical
construction concept for various crash scenarios. The
behavioural trends observed from this set of simulations are
used as basis for defining crash design targets for a new
profile based car body structure. The second set of FE
simulations is performed on the components of a profile
based car body structure. The data obtained from this set of
simulations are used to evaluate different analytical
methods available for predicting the behaviour of car body
components under crash loads. Regression analysis is
performed on these simulation results to formulate equations
that can be used for designing components of the new car
body structure. Application of this design approach is
demonstrated and validated by generating a concept design of
front end of a micro-sized electric vehicle.},
