Mechanisms kinematic analysis by geometric and computational approach

The kinematics of a four-bar mechanism and others extern elements using one developed method is investigated. The basic four bar mechanism is coupled with a sliding element in a straight line and another sliding element guided by a straight line coupled to a rotating connection. The positions, speeds and accelerations are investigated in the full possible cycle. The PC and the Excel spreadsheet are used for the kinematic solution and simulation of the mechanical system. The kinematic analysis is performed considering specified the initial and end angular positions of the input bar, with an established angular increment. The method used allowed to verify the kinematic of the mechanism with precision and also the working simulation and the visualization, making it a viable alternative and allowing the information of the results.
