Analisis Kekuatan Suspensi Pegas Daun Truk Dengan Metode Finite Element

Abstract

Leaf spring suspension is used on vehicles with a large payload capacity.The leaf springs provide reflections due to the load value received. It will experience the toughest conditions in the repeated compressive loads, so the potential to fail due to fatigue limit of the material through . With often hold large loads so broken on experience spring leaves.This study aims to determine how the modeling and the strength of the leaf spring suspension trucks using Finite Element Method. The first step begins with a rear axle load calculation ,then analyzed are static loads such as heavy vehicles . Then proceed with leaf spring suspension geometry modeling. After modeling the geometry, the next step is modeling the load and pedestal. Type pedestal modeling performed in this research is the foundation of the model using fixed pedestal and roller..From Finite Element Method is , it is known the power of truck leaf spring suspension.Maximum tension that occurs in the leaf spring suspension is 233 MPa. While the materials used have the yield strength of 1158 MPa. From these results it can be calculated that the resulting safety factor is 4,9.
