Abstract :
Taking Special Vehicle as an example, the research is made on dynamic virtual prototyping modeling and simulation of complex mechanical-electrical-hydraulic coupling system. Based on mechanical dynamic model and control and hydraulic schematic diagram, a mechanical-electrical-hydraulic coupling dynamic virtual prototyping model of Special Vehicle is built capitalizing on ADAMS, MATLAB/Simulink and Easy5 and validated with frequency spectrum analysis. On the basis of this model, the virtual tests are carried out in various typical working conditions, which include vehicle driving stability, vehicle unfolding and folding stability, etc. From these virtual tests, complete data are obtained and performance indexes achievability and adaptability to the environment of Special Vehicle are evaluated. Meanwhile, the research results have important significance for the simulation and optimization of complex mechanical-electrical-hydraulic coupling system.
