System Integration between Three-Dimen-sional-motion Software and Hydraulic Stewart Simulator

摘要

This paper presents an integrated design process and tests of a Stewart simulator with a virtual visualization tool, Virtools, to create and generate three-dimensional motions. An inverse kinematic algorithm is written to convert each visualized motion to the displacements of six cylinders in a Stewart motion simulator. Displacement information is then transferred through the User Datagram Protocol (UDP) to a personal computer which has LabVIEW software. An NI USB-6251 data-acquisition device interacts between the Lab-VIEW program and the hydraulic Stewart simulator. The approach presented in this paper to operate a Stewart hydraulic simulator can also be applied to other simulators.
