Abstract: Virtual Reality, robot technology and intelligent optimization method were applied to simulate the working process of a concrete pump car. Data reading from three-dimensional model, virtual environment creation and intelligent search with genetic algorithm were studied. The concrete pump car was modeled in 3DMAX, then it was imported into the virtual scene. The model can simulate the process of concrete pouring, through which search algorithm can be tested. A virtual reality system was developed with Visual C++ 6.0. The interface is friendly and authentic. The simulation suggests a new way to develop a concrete pump cars.
