Analysis of Roller Chain Drive System with Multi-Flexible Body Dynamics Methodology

Abstract

Abstract. Finite element method (FEM) was employed to analyze the roller chain drive system which complicated to determine various design factors. The multi-flexible body dynamics (MFBD) method was proposed to model and analysis the roller chain drive system. The roller chain which composed of plates, pins and rollers was meshed with solid elements under the convergence test. The eight tooth sprocket was modeled by rigid body to roll and contact with the roller chain. The dynamic load distribution of the roller chain on the rigid sprocket was compared with the analytical solution. The MFBD simulation results had a good agreement with analytic results which obtained an average error of 12.32%.

Research of the problem of optimization and development of a calculation method for two-stage chain drives used in heavy industrial vehicles in conditions of economic efficiency

“…Thus, the following advantages of chain drive can be noted: it is possible to transmit motion over long distances through chain drive; the geometric dimensions of the drive are smaller than those of the belt drive; the average value of the drive number is constant; efficiency factor is high; it is possible to transmit energy to several driven shafts through one drive shaft; less force is applied to the shafts in the chain drive than in the belt drive [5]. Chain drives are widely used in agricultural and lifting-and-shifting machines, oil drilling equipment, motorcycles, bicycles, cars [6].…”
