Abstract

In this study, the natural frequencies of Solaris 10 Solar Car’s 2018 and 2019-Model wheels were determined experimentally by the impact hammer test under free-free boundary conditions and the results were compared with the natural frequency results obtained using ANSYS FEA software. Comparing the numerical and experimental vibration analysis, a maximum percent error of 7.46% was observed. The 7th and upper mode frequencies of 2018 and 2019 wheel models were shown to be above 200 Hz and the experimental results were validated. After expressing the mode shapes in the ANSYS-Modal Analysis, a parametric study was performed for the 2019 wheel model using the ANSYS- Parametric Design. As a result of the parametric design, the mass of the 2019 wheel model was decreased by 6.5% while maximum equivalent von Mises stress was decreased by 2%. Thus, a lighter wheel design was obtained with ANSYS FEA software and maximum equivalent von Mises stress value was achieved to be below pre-defined limit of 120 (MPa).

Özet

Bu çalışmada, dönmeyen lastiksiz Solaris 10 güneş arabası jantının 2018 ve 2019 modellerinin doğal frekansları, serbest sınır koşulları altında darbe çekici testi ile deneysel olarak belirlenmiş ve sonuçlar ANSYS Sonlu Elemanlar Analiz yazılımında elde edilen doğal frekans sonuçları ile karşılaştırılmıştır. Sayısal ve deneysel olarak elde edilen doğal frekans sonuçları karşılaştırıldığında, maksimum yüzde 7.46 hata elde edilmiştir. Deneysel olarak elde edilen sonuçlar doğrulanmış ve 2018 jant modeli ile 2019 jant modelinin 7. mod frekans ve üstü frekanslarının 200 Hertz'in üstünde olduğu gösterilmiştir. ANSYS- Modal Analiz modülünde gözlemlenen mod şekilleri, yüksek genlik oluşturabilecek doğal frekanslar için gösterilmiştir. 2019 Jant modeli için parametrik CAD modeli kullanılarak bir tasarım optimizasyonu çalışması gerçekleştirilmiştir. Tasarım optimizasyonu sonucunda 2019 jant modelinin kütlesi % 6.5 azalırken, maksimum eşdeğer von Mises gerilmesi % 2 azaltılmıştır. Böylelikle, ANSYS Sonlu elemanlar analizi yazılımında parametrik çalışma ile daha hafif bir jant elde edilmiş ve maksimum eşdeğer von Mises gerilmesi 120 MPa'nın altında kalması sağlanmıştır.
