AE342: Modelling and Analysis Lab: Q1) RSSR

This document summarizes a practice session on spatial mechanisms that analyzed the RSSR and RGSR mechanisms. It includes plots showing the variation of the output link angle with the input for each mechanism. The conclusion states that the RSSR has 2 degrees of freedom while the RGSR has 1, and that replacing a spherical joint with a universal joint in the RGSR does not change the motion of the output link.

AE342: Modelling and Analysis Lab

Practice Session 04: Spatial Mechanism-RSSR

Rahul B (SC15B038) & Rahul Goud Togita (SC15B039)

Q1) RSSR

Plot 1: Variation of angle of output link with input for RSSR

Q2) RGSR

Plot 2: Variation of angle of output link with input for RGSR


Conclusion:

 In the RSSR mechanism, there are 2 degrees of freedom and in the RGSR mechanism
there is only one 1 degree of freedom.
 The movement of connecting link is restricted in second case because of lack of
availability.
 Even though one of the spherical joint is replaced by the universal joint, the motion
of the output link remains same which can be seen from above plots.
