Calculated Determination of Failure Loads of Leaf Springs Eyes at Collision of Truck with Anti-Ram Device

Abstract

Recommendations were developed for determining the strength indicators of the most loaded elements of the top spring leaves of the front suspensions of trucks based on computer simulation of the processes of destruction and the study of the mechanical properties of the material. The method was tested on the example of a standard spring design with two upturned eyes at the front ends. The proposed guidelines for determining the indicators of the strength of the springs eyes can be used in the design of road blockers for the calculation of the existing loads.
