The Fatigue Test Analysis of Torsion Bar under Different Material Conditions
In order to analyze the fatigue performance of the torsion bar components under different conditions,the fatigue stress of the torsion bar and the common fatigue fracture parts in the actual working process are first analyzed.Several main factors affecting the fatigue performance of the torsion bar are further analyzed.Material characteristics,structural design,processing methods and heat treatment forms.By setting the fatigue tensile test,the fatigue properties of the torsion bar under different heat treatment conditions and processing conditions are compared.The characteristics of the torsion bar after austempering heat treatment are obviously better than those after QT heat treatment.The processing technology has no obvious change in the fatigue characteristics of the torsion bar,and the fracture is the thin rod part.Through the analysis,it is expected to guide the optimization of the actual process of the torsion bar in the production and manufacturing,and then improve the overall stiffness and reliability of the torsion bar.
