Abstract

In this study, a steering system developed using a six-bar flexible mechanism is examined. The design consists of short-length flexible links and is designed as a single piece. Significant reduction in the number of parts compared to traditional systems is observed. The mechanism is designed to operate in a planar manner and is suitable for providing Ackerman geometry. In the study, the mechanism is first dimensioned for rigid mechanism synthesis and then modeled as a flexible mechanism. After the strength analysis, the results are validated by finite element analysis. A prototype is produced and theoretical results are compared with experimental data. Additionally, kinematic analyses are performed, and motion capabilities are verified. The study presents a suitable prototype model for a vehicle steering system that can be preferred in applications requiring low-cost production.

ALTI ÇUBUKLU BİR ESNEK MEKANİZMA KULLANILARAK ARAÇ YÖNLENDİRME SİSTEMİ GELİŞTİRİLMESİ

Abstract

Bu çalışmada, altı çubuklu esnek bir mekanizma kullanılarak geliştirilen araç yönlendirme sistemi incelenmektedir. Tasarım, kısa boylu esnek mafsallardan oluşmaktadır ve tek parça olarak tasarlanmıştır. Geleneksel sistemlerle karşılaştırıldığında parça sayısında ciddi bir azalma gözlemlenmiştir. Mekanizma düzlemsel olarak tasarlanmış olup, Ackerman geometrisini sağlamak için uygun bir modeldir. Çalışmada, mekanizma öncelikle rijit mekanizma sentezi için boyutlandırılmış ve daha sonra esnek mekanizma olarak modellenmiştir. Dayanım analizi yapıldıktan sonra sonuçlar sonlu eleman analizi ile doğrulanmıştır. Prototip üretilmiş ve teorik sonuçlar deneysel verilerle karşılaştırılmıştır. Ayrıca, kinematik analizler yapılmış ve hareket kabiliyetleri doğrulanmıştır. Yapılan çalışma, düşük maliyetli üretim gerektiren uygulamalarda tercih edilebilecek bir araç yönlendirme sistemi için uygun bir prototip model sunmaktadır.
