Design Optimization of Leaf Spring using Excel Solver Tool

Leaf springs are widely used in automobile suspension systems.The main aim of present work is to develop software for design of leaf spring. Leaf Spring is a critical load bearing element that connects wheel to the chassis in an automobile application. The Suspension leaf spring of one of the potential items for weight reduction in automobiles in order to achieve increased fuel efficiency and improved ride characteristics.Programming the computer to handle a design work involves the development of program in line with the design procedures, coding the instruction set with a high level programming language.Developed software was able to design leaf spring while varying so many loading conditions such as static load condition, bending load condition, various dimensions of spring steel bar. They found the optimized dimensions to withstand the loadings and right combination of width and thickness to spring length of various leaves to prevent excessive deflection.
