Abstract
In process of vehicle crash simulation analysis, pre-processing
takes about 40%~60% of the work time. Shortening period of data
preparation of crash simulation is an efficient way to speed up CAE
analysis. For collaborative management of FEA model, it is usually
divided into some sub-systems including BIW, enclosure, front and
rear suspensions. After building individual model for each
sub-system, all sub-models are assembled into a full vehicle. There
are lots of hand operations in this period, such as mesh quality
checking, materials & properties updating, treatment of the
assembly connection. Those jobs are tedious and less efficient. In
this paper, both the development procedure of Geely car and
requirements of CAE simulation are considered to improve vehicle
safety performance, NVH & structure strength. A semi-automatic
assembly-aided system is developed for assembling full-car crash
model. Mesh quality batch checking, materials & properties
batch updating and model rapid assembly are all included.
Pre-processing saves 50% of processing time than before and makes
CAE simulation much more efficient in Geely car development.
