Vibrational Durability Test Methodology for an EGR Cooler

Abstract

EGR Cooler is one of the key automotive components which use coolant to reduce exhaust gas during discharge through the air induction system. These automotive components are exposed to different types of vibrations such as simple sinusoidal or random excitations. This work presents vibration durability test methodology which is used for the EGR cooler of Heavy Duty Vehicle. Test set-up and procedures are developed to assess durability performance of the EGR on the electrodynamic shaker. Sine, random and sine on random test profiles are compared to show their effect of the EGR durability. In addition effect of the excessive test profiles are observed on the EGR in this work.
