The purpose of this thesis was to obtain the most optimal cam profile by comparing three design configurations, to simulate the forces exerted by the foot when walking using a cam-follower system. The procedure to follow was the analysis and synthesis for the design of mechanisms. The proposed mechanism consists of a cam-follower system (plunger) that generates pressure to simulate the force exerted when walking. It began by dividing the diagram that establishes the force of the human foot in walking into 5 segments, using the graphic method, the approximate values are found at the characteristic points. The pressures were determined and using the pressure – volume relationship, the displacements in each segment were calculated. Using the Dynacam software, data was entered for the 3 design configurations (cycloidal, modified trapezoidal, and modified sinusoidal) and the characteristics...
