Abstract:

Because of some unique advantages, the Stewart machine tool is of attracting prospects and gaining widespread concern.With the help of the theory of kinematics on multi body systems, this paper analyzes the motion of typical types of Stewart machine tool mechanisms; equations of kinematics of Zero grade, First grade are established; Jacobian matrix is derived.A general multi body analysis software package is used to calculate and simulate the motion of the Stewart machine tool.

Key words: Stewar t machine tool, kinematics, multi-body syst ems
