Ağır Hizmet Aracı Bütünleşik Fren Diski ve Poyra Çiftinin Soğuma Süresinin Sayısal ve Deneysel Olarak İncelenmesi
Öz
Bu çalışmada, geleneksel ağır hizmet aracı fren diski ve poyra çiftine göre ağırlık ve maliyet avantajı sağlayan bütünleşik fren diski ve poyra çiftinin soğuma süresi sayısal ve deneysel olarak incelenmiştir. İlk aşamada, havalandırmalı fren diski ve poyra çiftlerinin atalet dinamometresi üzerinde soğuma süresi deneyleri farklı taşıt hızları için gerçekleştirilmiştir. İkinci aşamada, atalet dinamometresi üzerinde gerçekleştirilen soğuma süresi deneylerinin sınır koşulları göz önünde bulundurularak, fren diski ve poyra çiftlerinin zamana bağlı termal analizleri gerçekleştirilmiştir. Deneysel soğuma süresi sonuçları sayısal sonuçlarla karşılaştırılarak, sayısal çalışma doğrulanmıştır. Geleneksel fren diski ve poyra çiftine göre bütünleşik fren diski ve poyra çifti ile soğuma süresinde % 29,8 iyileşme elde edilmiştir. Ayrıca, geleneksel tasarıma göre fren diski ve poyra çifti toplam ağırlık indirgemesi 10 kg (%15,2) olarak elde edilmiştir.

Numerical and Experimental Investigation of Cooldown Period of Heavy-duty Integrated Brake Disc and Hub Pair
Öz
In this study, the cooldown period of the integrated brake disc and hub pair, which provides weight and cost advantage compared to the traditional heavy-duty brake disc and hub pair, was investigated numerically and experimentally. In the first stage, cooldown period experiments of ventilated brake disc and wheel hub pairs on an inertia dynamometer were carried out for different vehicle speeds. In the second stage, transient thermal analyses of brake disc and hub pairs were carried out, in consideration of the boundary conditions of the cooldown period experiments performed on an inertia dynamometer. The numerical study was validated by comparing the experimental cooldown period results with the numerical results. The cooldown period was improved by 29.8 % for the integrated brake disc and hub pair compared to the conventional brake disc and hub pair. In addition, total weight reduction in brake disc and hub pair was achieved by 10 kg (15.2 %) according to the conventional design.
