Abstract
Abstract A planar mechanism with three moving parts is connected to a cam. The mechanism is consisted from crank arm, connecting rod, flat-faced follower, polydyne cam, and two guides with clearance. The investigation of the dynamic simulation of the contact force between the cam and the follower is considered in the presence of crank arm and connecting rod mechanism. Nonlinear response of the contact force is simulated at different guide width of the follower guide and at different cam speeds. SolidWorks program is used in the calculation of contact force at different cam speeds and different guide’s width. The nonlinear dynamics simulation of the planar mechanism is described using Lyapunov exponent parameter, Poincare’ map, Fast Fourier Transform, and phase-plane mapping. Local Lyapunov exponent is calculated using the MatLab code of the dynamic tool algorithm based on the values of time delay and embedding dimensions. The amplitude of Fast Fourier Transform is determined using the analysis of power spectrum while phaseplane diagram is drawn using the relation between the contact force and its variation.
