A historical review is made of the methods adopted in vehicle
design.
This is divided into two sections, vehicles with chassis frames
and integral structures.
Complete solutions have been obtained for all types of chassis frames
by Erz and the results of this work are given. The simple frame structural
analysis has been extended for buses, with semi-integral and integral
construction.
Private car structural analysis has been very approximate using
pencil and paper method4 various approaches have been tried with little
success. The advent of the digital computer has made the analysis of
such complex structures possible and the two basic methods of ‘displacements’
and 'force’ are described. The matrix force method due to Argyris is
treated in detail with a complete analysis of a simplified box van structure
under idealised loading. This method has been chosen for economy in computer
space and its application to a more complex structure, an integral Land Rover,
is indicated.
With the advent of very large computers it is probable that displacement
methods will, take precedence as less work in 'choosing' the idealisation and
redundant systems is involved. |
