High performance automotive chassis design: a topology optimization based approach

Abstract

Automotive chassis design in view of car weight reduction is a challenging task due to the many performance targets that must be satisfied, in particular in terms of vehicle safety. In this paper a methodology for automotive chassis design in involving optimization techniques is presented. In particular, topology, topometry and size optimizations are coupled with fem analyses and adopted in cascade for reaching an optimum chassis configuration. The methodology is applied to the design process of a rear-central engine high performance vehicle chassis. The objective of the optimization process is the chassis weight reduction, yet in fulfilment of structural performance constraints as required by Ferrari standards. The results demonstrate the general applicability of the methodology presented for obtaining the general trusses layout and thicknesses distribution of the structure. The numerical model at this stage shows a significant weight reduction when compared to the chassis of the Ferrari F458 Italia

Topology optimization of 3D self-supporting structures for additive manufacturing

“…After its conception in the late 15 80's [6], TO has developed at a rapid pace and continues to form an area of active research. In various branches of industry, TO is an established part of the design process [7,8]. For an overview of the field, the reader is referred to recent reviews by Sigmund and Maute [9] and Deaton and Grandhi [10].…”

Weight Reduction in Brake Disc Using Topology Optimization

“…This method of optimizing the existing geometries without sacrificing performance requirements has many applications. Cavazzuti et al [2] used this method and designed the chassis of an automobile. Kaya et al [3] with the help of this technique redesigned a clutch fork.…”

Multi-objective optimisation of vehicle bodies made of FRP sandwich structures

“…Although this is a roughly simplified way to simulate a front impact scenario, it is anyway expected that the applied static force will unveil the load paths by increasing the thickness of specific layers as required in order to satisfy the displacement constraint of point B. Other authors have used the same approach for single-objective topology optimisation [20].…”
