“…The ability of the camshaft to withstand the torque reflects the strength of the camshaft connections. Using the relation between the friction coefficient and the interference given by equation (6), the friction coefficient is obtained. The simulation for the torque capacity testing is carried out, with different radial interference values, 0.02, 0.025, 0.03, 0.035, 0.04, 0.045, 0.05, 0.06, 0.07, 0.08, 0.09, and 0.1 mm.…”

The maximum contact strength stress in the shrink-fit camshaft assembly was obtained by finite element method. It is found that there is a maximal radial interference, below which there is no plastic deformation and which can be used as the limitation for the radial interference. In our case, the maximal radial interference is 0.08 mm. Then, based on Lamé's equation and experimental data, the relationship between friction coefficients on the contact surface of shrink-fit camshaft and the radial interference is established. For the shrink-fit camshaft in our case, the range of friction coefficient is 0.14-0.19. After that, the relationship between the torque capacity and the radial interference for the shrink-fit camshaft is established by the finite element model for torque capacity testing based on the friction coefficient obtained before. There is a positive correlation between the radial interference and the torque capacity, but their relationship is not simple linear, similar to the exponential relationship. The slope of the torque capacity curve decreases gradually with the interference increasing. In the elastic range, the results obtained from experiment and simulation are in good agreement, with a maximum relative error of 8.1%. The results of our study are expected to design and manufacture for shrink-fit camshaft.

In tube hydroforming process (THP), two types of loading, internal pressure and axial feeding and in particular the combination of them, are needed to feed the material into the cavities of the die to form the workpiece into the desired shape. If the variation of pressure versus axial feeding is not determined properly, the workpiece may be buckled, wrinkled or burst during THP. The appropriate variation is normally determinedby experiment which is expensive and time-consuming. In this work, numerical simulation using Johnson-Cook models for predicting the elasto-plastic response and the failure of the material are employed to obtain the best combination of internal pressure and axial feeding. The numerical simulations are examined by a number of experiments conducted in the present investigation. The results show very close agreement between the numerical simulations and the experiments, suggesting that the numerical simulationsusing Johnson-Cook material and failure models provide a valuable tool to examine the different parameters involved in THP.
