Optimizing Engine Coolant Hose Joint Performance through Taguchi Design of Experiments and Computer-Aided Engineering Analysis

This article presents a design of experiments (DOE) approach to analyze automobile engine coolant leakage from hose joints. The data includes force measurement at hose joints through physical validation and computer-aided engineering (CAE) simulation results. The proposed approach involves utilizing digital validation data, which simulates the entire experiment using CAE. The novelty of this approach lies in its reliance on digital validation data rather than conventional physical measurements, thus providing cost and time savings for the organization.

In this study, the authors investigated the force at the coolant hose joint, which results in oil leakage as the response variable. Nine independent factors were evaluated in this experiment. The study concluded through the identification of critical parameters and opposed regression model to predict force at hose joints.
