Abstract
In places where there is a space restriction, a foldable stair can be used. In accordance with this, we have simulated a mechanism in which the unfolding and folding of the stair is due to the linear motion of the slider at one end. The effect of the change in length of connecting rod that converts linear motion to rotary motion is to be analyzed. Here we consider 10 different lengths of the connecting rod. The force needed to move the slider is measured using MSC ADAMSTM software in each of these cases. Then a linear actuation circuit for the slider using a double acting cylinder is designed and simulated using Festo FluidSIMTM software. Thus in this paper we present the effect of change in length of the connecting rod by considering the force needed for actuation and the linear distance to be moved by it.
