Kinematic analysis of one degree of freedom mechanisms using the SolidWorks and the MATLAB

Resumo

The following article intends to present the kinematic analysis of three different mechanisms with one
degree of freedom, being one four-bar mechanism, one quick return mechanism, and one slider-crank mechanism
using different methods, first the Solidworks motion study tool, and afterwards codes developed in the MATLAB.
To determine the dimensions of the elements were utilized a shaping machine for the quick-return mechanism,
and the LS3 engine for the slider-crank mechanism. Graphics and maximum values of displacement, velocity, and
acceleration for specific frequencies of rotation of the crank were shown, and the results were validated by
comparison. Furthermore, some kinematic details of the mechanisms were analyzed, including the ratio between
the time of advance and return of the quick-return mechanism. The same results - extreme values and graphics -
were found by both methods, which demonstrates that they were correct.
