Dynamics of training simulator for mobile elevating platforms

摘要

Intervention in high place such as buildings are requiring hydraulic elevating platforms commonly used for assembling outside covers, washing windows, as well as inspection and safety for repairs, rescuing persons and fire-fighting. As these platforms are aimed at providing a complex service, their operation, even when simplified by adequate design, is requiring a sophisticated action which has to be learned by operator using a concept of a man-in-the-loop simulator to be used in operator training for time-critical and accurate boom maneuvers. From various constraints the hardware consists of a boom platform mounted on a 3d Stewart platform, and virtual engineering software is used to visualize the working environment on wall screens. As a consequence for validation of the simulator, a strong limitation is coming from the needs of a simulation model satisfying contradictory properties of accuracy and real time computation which is transforming large boom movements to produce restricted motion in the Stewart mechanism.
