摘要

An excavator simulator has been developed in this paper for training human operators and evaluating control strategies for heavy-duty hydraulic machines. In such a system, the operator controls a virtual excavator by means of a joystick while experiencing realistic operating feelings through force feedback, graphical displays, and sound effects in virtual operating environments. A GPU (graphics processing unit)-based, terrainrendering methodology is adopted to create a realistic visual appearance of different operation regions on terrain such as excavated areas and dumped soil areas during the excavator simulation. The digged soil in excavator's bucket is considered made up of large amounts of particles and each soil particle has attributes of position, velocity and mass. Particle system is applied for in charge of managing the soil particles and produce the dynamic interaction visual effect of excavator's soil dumping. The graphic simulation of excavator is realized in a PC with satisfying frame rate up of 60 per second, which provides a low-cost solution not only for simulator of the excavators, but also for other construction vehicles.
