Abstract |
|
|
| Taking Special Vehicle as an example, the research is made on dynamic virtual prototyping modeling and simulation
of complex mechanical, electrical and hydraulic integrated system. Based on hydro-pneumatic spring model, ”magic formula” tire
model, road spectrum model, flexible body model of key components, and vehicle control-hydraulic model, a mechanical, electrical
and hydraulic coupling dynamic virtual prototyping model of Special Vehicle is built capitalizing on dynamic simulation analytical
software ADAMS and control system simulation analytical softwareMATLAB/Simulink, and the virtual prototyping model is validated
and verified by the physical test data. On the basis of the built prototyping model, the virtual tests are carried out in various typical
working conditions, which include vehicle driving stability, vehicle unfolding and folding stability, etc. The complete data are obtained
from virtual tests and the performance indexes achievability and adaptability to the environment of Special Vehicle are evaluated.
The correlation of the main design parameters and the performance indexes is established, which provides basic technical support
for optimizing its overall design parameters. The research results have important significance for the simulation and optimization of
complicated mechanical, electrical and hydraulic integrated system. |
