Ever shorter times to market and increasingly exacting requirements for chassis system functionality necessitate an efficient and intelligent development process. 'ZF Lemförder Fahrwerktechnik' and 'Institut für Kraftfahrwesen Aachen (ika)' have jointly elaborated a calculation tool known as ABE for use in suspension development, including kinematic design for axle systems. The tool is modular and has been extensively optimized over an extended period of time. The virtual product environment that consolidates a host of individual axle development steps into a single process is described in the paper. The kinematics for new designs are defined using the ABE program. An extended joint angle module allows for determination, early in the development process, of the joint angles that occur in a jounce/rebound and steering configuration. A subsequent step involves elastokinematic design via synchronization of CAD and multibody simulation applications, which allows for the modeling of numerous load scenarios. The results of these simulations are transferred to an FEM environment in which individual component loads are simulated in greater detail and recursive component topology modifications can be realized. In this case, optimized components are retrieved from an axle and component database with a view to reusing identical parts wherever possible. The VPE process has been extended by a kinematic and elastokinematic optimization function that enables accelerated and efficient axle configuration for target ride and comfort dynamics that also allow for the specified package.
