Chassis tuning influence in vehicle durability loads 2018-36-0060
During a vehicle development, several chassis components suffer tunings, changing its specification as stiffness, damping, preload, etc to attend Handling, Ride and NVH requirements.
In other hand, it can change the loads environment and consequently the fatigue life of the components. The objective of this study is to understand the impact in the vehicles loads that can be caused by a suspension tuning, measuring the sensibility of each component tuning.
The possible differences of its behavior, in terms of pseudo damage, will be calculated trough Rainflow technique from an original signal obtained with the usage of virtual road loads data acquisition. For that will be considered all possible required specifications of chassis components since the beginning of the project until the end.
