Topology Optimization of Leaf Spring Brackets in Truck Suspensions
Abstract
Through the use of structural optimization methods, it can help to design brackets as light, strong and safe. Leaf spring brackets are an important part used for attaching and fixing leaf springs in vehicle suspension systems. The design of the leaf spring brackets has a significant impact on the suspension system performance, handling, driving comfort, and safety of the vehicles. In this study, first of all, the materials used in the leaf spring brackets were investigated. After the material analysis, the most suitable material for the alternative leaf spring brackets developed for the suspension system of a commercial vehicle was determined. Modeling of various designs of these leaf spring brackets was done in Catia V6, a package program. After the modeling process was done in the package program, static analyses were made with the Ansys Finite Element Analysis program. As a result of the examination of the leaf spring brackets, the alternative spring bracket design of the truck, which is a heavy tonnage commercial vehicle, was developed and the topology optimization of the bracket was carried out according to the results of the analysis with the ANSYS Finite Elements program. Thus, the selection of the appropriate leaf spring bracket for this selected vehicle has been carried out.
