Title: A Numerical Analysis of Multi-Leaf Spring Strength
Author(s): Jakub Soltysiuk   Wieslaw Krason            

Abstract: This paper presents the results of a dynamic loading numerical simulation of double multi-leaf spring with bi-linear elasticity characteristic curve. The solution was obtained by using a solid spring model. A nonlinear analysis was performed in MSC Dytran. Construction resultant displacement maps were determined as a result. The conducted studies aimed at obtaining a close correlation between numerical analysis and real experiments with multi-leaf spring.

Keywords: multi-leaf spring of truck, FEM, numerical analysis.
