Rotational motion of a Stewart platform with solid works modelling and matlab simulation

In this paper the solid work modelling of a Stewart Platform for rotational motions has been done. Three basic rotational motions as roll, pitch and yaw of sinusoidal motion with different amplitude have been studied with solid works modelling. The inverse kinematic modelling has been formulated in this work to find out the individual piston motion of the Stewart Platform. The corresponding piston motion have been extracted for the rotational motions and depicted with help of Matlab Simulation. The maximum range of the platform motions have also been established and tabulated which can be implemented in real time applications. The maximum possible range of the roll motion is with 18° amplitude, pitch motion with 17° amplitude and yaw motion with 14° with the available piston stroke length of 150 mm.
