Development of the calculation method for the loads acting on the lower control arm in vehicles

Abstract

In this study, an analytical static model was created by using the balance configuration of the suspension system, which has an active role in vehicle comfort and safety. In some literature studies, it is accepted that the axle carries a load, while in others it is accepted that it does not carry a load. For this reason, the mathematical model was evaluated for two cases, and the equations were examined separately according to the axle load bearing and non-load bearing conditions. In the study, the static equilibrium conditions of the suspension system were taken into account in detail, and the analytical model was expressed with a general formula. In this way, the loadings affecting the suspension arm and the limit conditions of the suspension arm have been revealed in MacPherson suspension systems. With the resulting equations, MacPherson revealed the loads acting on the suspension arm in the suspension system. With this study, usable equations have been revealed for researchers who will carry out strength analysis and optimization studies on such suspension arms.

Araçlarda askı koluna etki eden yükler için hesaplama yönteminin geliştirilmesi

Öz

Bu çalışmada araç konfor ve güvenliği için etkin bir rolü olan süspansiyon sisteminin denge konfigürasyonu kullanılarak analitik açıdan bir statik modeli oluşturulmuştur. Bazı literatür çalışmalarında aksın yük taşıdığı kabul edilirken bazılarında ise yük taşımadığı kabul edilmiştir. Bu nedenle matematiksel model iki durum için değerlendirilmiş, denklemler aksın yük taşıması ve taşımaması durumlarına göre ayrı ayrı incelenmiştir. Çalışmada süspansiyon sistemine ait statik denge şartları kapsamlı bir şekilde dikkate alınmış, analitik model genel bir formülle ifade edilmiştir. Bu sayede MacPherson süspansiyon sistemlerinde askı koluna etki eden yüklemeler ve askı kolu sınır şartları ortaya çıkarılmıştır. Sonuç olarak elde edilen denklemler ile MacPherson süspansiyon sisteminde askı koluna etki eden yükleri ortaya koymuştur. Bu çalışma ile bu tarz askı kolları üzerinde mukavemet analizi ve optimizasyon çalışmaları yapacak araştırmacılar için kullanılabilir denklemler ortaya çıkarılmıştır.
