Experimental and Numerical Stress Analysis of Involute Splined Shaft

Abstract

In this study, the induced splined shaft teeth contact and bending stresses have been investigated numerically using finite element method(Ansys package version 11.0) with changing the most effecting design parameter,(pressure angle, teeth number, fillet radius and normal module), for internal and external splined shaft. Experimental work has been achieved using two dimensional photoelastic techniques to get the contact and bending stresses; the used material is Bakelite sheet type “PSM-4”.The results of numerical stress analysis indicate that, the increasing of the pressure angle and fillet radius decrease the bending stress and increase the contact stress for both internal and external spline shaft teeth while the increasing of the normal module and teeth number decrease the contact and bending stresses

Design Method and Teeth Contact Simulation of PEEK Involute Spline Couplings

“…Faidh-Allah et al used the finite element method to conduct numerical research on the induced design parameters of the internal and external spline shafts and compared them through experiments to obtain the stress variation rule. [ 24 , 25 ]. The aforementioned research has provided a robust foundation for investigating the contact properties of involute splines pairs fabricated using PEEK-based materials; researchers have presented excellent results in the fields of splines design, dynamic properties, frictional wear, and fatigue life.…”
