? 2022In this work was analyzed the fatigue resistance performance of several universal cardan joint for direction column in automotive application. For this purpose, were performed a simulation by finite element (FEA), laboratory fatigue tests and Weibull distribution reliability analyses to evaluate the fatigue life performance of universal joints in according with MAN PV 2892 BR criteria. These analyses were made taking into account a torsional working load in addition to torque applied in the fasten clamp yoke region with the shaft. Additionally, mechanical stakes tests retention was performed in order to attend the requirements of MAN PV 2892 BR. The results indicate that although laboratory fatigue testing exceeds 500,000 cycles, there is an 8% probability that failure will occur at less than the required number of cycles. Thus, the material design and manufacturing process employed, mainly in relation about the amount and mechanical stakes locations and fork roughness, as well as the microstructure inclusions content could bring significant gains in fatigue life in this automotive component.
