Course project & Term paper
The course project should be done individually. Its purpose is to reinforce the learnings
from the course. It requires application of the thoery and methods taught in the course
to a compliant mechanism design. The mechanism should be 3D-printed and tested. A final presentation
is needed at the end of the semester.
The student is expected to browse through the literature to identify a paper of interest.
The paper should have been published in 2017 or after. A report is to be submitted based on
student's understanding of the paper. It should include (i) a summary of the paper
(written in own words and not copied from the abstract or conclusions, (ii) novelty of the paper,
(iii) implementation of the main components of the paper, (iv) critique of the paper (limitations,
unclear parts, etc.), and (v) ways to go beyond the paper.
Project ideas
Desinging and making an FaCM to break a dried beetle nut (half or full) using hand-force
Non-dimensionalization of a compliant mechanism consisting of at least six beam segments for displacement and stress responses
Validation of the pseudo-rigid-model using finite element analysis for a foour-bar linakge that has the coupler body fixed to the input and output cranks connected to the frame with revolute (i.e., pin) joints
Mechanical advantage plots (MA1, MA2, and MA3) for any two compliant gripper mechanisms in the M2D2 collection; include also the sensitivity of MA w.r.t. workpiece stiffness; but use geometric nonlinearity for all. Compare with linear analysis.
Graphical user interface for the instant-centre method of designing compliant mechanisms using Matlab or any other software
Complete design of a two-axis micromachined accelerometer using DaCMs and xy-dcoupling
