“…multibody simulations are carried out using the program described in [11,12]. In the multibody model the mass of the chain is lumped at the roller center locations, and springs and viscous dampers with constant stiffness-and damping coefficients model the chain links.…”

An exact and approximate kinematic analysis of a roller chain drive modeled as a four-bar mechanism is presented. The span connects the sprockets such that they rotate in the same direction, and the sprocket size, number of teeth, and shaft center distance can be arbitrary. The driven sprocket angular position, velocity and acceleration, as well as span length, is calculated and their (discontinuous) variation with driver angular position and main design parameters is illustrated. Kinematic predictions for the chain span motion are compared to results of multibody simulation, and there is seen to be very good agreement. All together this gives new insights into the characteristics of chain drive kinematics and the influence of main design parameters.

“…Numerical analysis of roller chain drive systems has been developed using a multibody modeling approach by Pedersen et al [11], which can take into account non-linear dynamic coupling, exact tooth geometry and impact phenonema [12]. A general methodology for planar models of multibody chain drives has been suggested by Pereira et al [13].…”

“…Simulation results are obtained using a simulation program which include dynamic effects, flexible contact, and the exact geometry of the sprocket teeth [8,9]. These results demonstrate that a real roller chain drive must include compliant components for a tensioned chain to wrap around rotating sprockets, as the sprockets are effectively eccentric.…”

Enhanced chain dynamics in loop-sorting-systems by means of layout optimization and a kinematic model of the polygon action

Poor dynamics owing to polygon action is a known concern in mechanical applications of closed articulated chains. In this paper a kinematic model of the polygon action in large chains of loop-sorting-systems is proposed. Through optimization techniques the chain dynamics is improved by minimizing the polygon action using a parametric model of the track layout as design variables. Three formulations of the kinematic polygon action are tested on an average sized planer tracks layout to find a superior model. Verification of the proposed optimization method is performed using a state-of-the-art multi-body simulation model of the chain dynamics.
