Mechanism Design and Kinematic Analysis

6 weeks · 0 milestones

Design a mechanism for a specific function and perform a complete kinematic analysis covering: a kinematic diagram showing all links, joints, and degrees of freedom with Gruebler's criterion applied, position analysis (at least 3 positions in the motion cycle), velocity and acceleration analysis for the critical position, force analysis under the specified load, and identification of any design constraints or singularities (positions where the mechanism locks or becomes indeterminate). The mechanism must be non-trivial — at least a 4-bar linkage or equivalent complexity. Preferred proof: a mechanism designed for a real application with physical prototype evidence. Accessible alternative: kinematic analysis of a documented mechanism scenario using FreeCAD's kinematic analysis module or hand calculation with velocity polygon diagrams — equivalent rigor required. Proof artifacts: the kinematic diagram and analysis (design artifact) and the force analysis results with documented methodology (analysis artifact). Verification: a mechanical engineer reviews the kinematic analysis — 'what is the mechanical advantage at this position, and how does it change across the motion cycle?' — requiring you to reason from your own analysis.
