Research on motion control technology for virtual assembly platform

Abstract

This article mainly focused on interactive virtual assembly platform with interactive technology and motion control technology. Basing on the physical properties of the object, the authors put forward a method that combines dynamics and particle spring principle to realize the interactive motion control of flexible object on the virtual assembly platform. It adopts the node matrix operation method to realize the real-time assembly and disassembly. A 3D graphics engine tool Open Scene Graph (OSG) is used to complete the development of interactive virtual assembly and virtual disassembly platform of a crane. It realize the select, drag, assembly and disassembly of interactive parts. The physical properties of the object is displayed by physics engine It realizes the motion control of flexible object. The automatic assembly and roam of parts in the scene can be realized by using the function of event callback and update callback. © 2013 Springer-Verlag.
