Analysis of Cord-Reinforced Poly-Rib Serpentine Belt Drive With Thermal Effect

Abstract

This paper investigates the operation of an automotive poly-rib serpentine belt system. A three-dimensional dynamic finite element model, consisting of a driver pulley, a driven pulley, and a complete five-rib V-ribbed belt, was created. Belt construction accounts for three different elastomeric compounds and a single layer of reinforcing cords. Rubber was considered incompressible hyperelastic material, and cord was considered linear elastic material. The material model accounting for thermal strains and temperature-dependent properties of the rubber solids was implemented in ABAQUS∕EXPLICIT code for the simulation. A tangential shear angle and an axial shear angle were defined to quantify shear deformations. The shear angles were found to be closely related to velocity variation along contact arc and the imbalanced contact stress distribution on different sides of the same rib and on different ribs. The temperature effect on shear deformation, tension and velocity variation, and contact stress distribution was investigated and shown in comparison to the results for the same system operating at room temperature.

Finite element analysis of V-ribbed belt/pulley system with pulley misalignment using a neural-network-based material model

“…The merit of the method is that it can approximate the test data much more accurately than any available model. Song et al [14,15] verified the accuracy of this model through analysis of cord-rubber serpentine belt. This methodology, hence, is adopted in the present study to derive the hyperelastic constitutive material law for rubber compound used in ABAQUS/Explicit algorithm.…”

Mode-I fatigue crack growth analysis of V-ribbed belts

“…The pulleys were considered rigid surfaces and the incompressible form of the Ogden strain energy potential was used to model the belt elastomer compound. Shen et al [2] proposed a neural network based material model for rubber; Song et al [3] performed the thermal-mechanical finite element analysis of a two-pulley V-ribbed belt drive system. The temperature effects on stresses, strains, and belt-pulley contact slip rates were studied in detail.…”
