Vehicle dynamics CAE capabilities has increased in the past few years, specially, for handling and steering attributes. However, secondary ride simulations are still highly depended on the tire model. Such tire model must be capable to simulate high order phenomenon such as impact and harshness transmissibility in three directions. In order to gather tire information sufficient to cope with these phenomena, one needs to perform a series of specific tests, and so be able to build the intended tire model. Still, there could be correlation issues. This whole process takes a lot of time and resources. This article presents a semi-analytical approach, using data gathered via wheel force transducers (WFTs) that are typically used for load cascading and durability purposes. The method main advantage is that since it relies on measured data at the wheel center, it is independent of a tire model, and, as such, it demands less time and resources.

This work describes the studies performed using finite element analysis models regarding to the development of an automotive suspension inner joint forming and disassemble (pullout) processes using the software MSC.MARC. The simulation performed involves plastic deformation and contact interaction of different parts in order to represent the steps of the assembly process and the inner joint pullout test. The results shown here were validated by confrontation with experimental data and then used to predict the structural behavior along the assembly process. The stress state after assembly and the required load to break down the inner joint (pullout force) had to satisfy specific design requirements.
