Simulation of the Presta process – Transfer of deformation history

Simulation of the Presta process – Transfer of deformation history The Presta joining process is the world's leading manufacturing method for assembled camshafts. It is a multi‐stage forming process separated in different steps. First, the rolling of the shaft creates a local widening of the intended cam seat. Within the subsequent joining process, the cam is forced onto the widened cam seat to form a tight fit. The two substeps are modelled and simulated using FEM. Within the process large local deformations occur, which requires an appropriate material model. The phenomenological material formulation of finite strain viscoplasticity implemented in the introduced simulation model enables the transfer of the deformation history to a new reference configuration. Hence, at the change of simulation models this feature is applied by passing the material model's internal state variables of the rolling step to the initial FE‐mesh of the joining step. This work shows the simulation models of the Presta joining process and gives a detailed insight into the change of the reference configuration. (© 2017 Wiley‐VCH Verlag GmbH & Co.

Abstract

The Presta joining process is the world's leading manufacturing method for assembled camshafts. It is a multi‐stage forming process separated in different steps. First, the rolling of the shaft creates a local widening of the intended cam seat. Within the subsequent joining process, the cam is forced onto the widened cam seat to form a tight fit. The two substeps are modelled and simulated using FEM. Within the process large local deformations occur, which requires an appropriate material model. The phenomenological material formulation of finite strain viscoplasticity implemented in the introduced simulation model enables the transfer of the deformation history to a new reference configuration. Hence, at the change of simulation models this feature is applied by passing the material model's internal state variables of the rolling step to the initial FE‐mesh of the joining step. This work shows the simulation models of the Presta joining process and gives a detailed insight into the change of the reference configuration. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
