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 level of chaos is investigated based on the value of the correlation dimension. Local and global embedding dimensions described the exponential function of each point of the contact force with respect to the state space domain. An average mutual information algorithm is used to calculate the value of time delay. Time delay, decorrelation time, and ‘bad’ predict time are used to calculate local, global, and correlation embedding dimensions. SolidWorks program is used in the calculation of contact force at different cam speeds and different guides’ widths. The algorithm code of the dynamic tool is used to calculate local, global and correlation dimensions. Local Lyapunov exponent is calculated using MatLab code of the dynamic tool algorithm based on the values of time delay, local and global embedding dimensions. 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.
