Kasis Profilinin Pasif Süspansiyon Sistemli Çeyrek Araba Modeli Kullanılarak Sürüş Konforuna Etkisi

Sürüş konforu sürücü sağlığı ve araç sürüşünün daha güvenli olması için önemli bir faktördür. Yol profiline bağlı olarak araç içi vücut ivmelenmesi azaltarak sürüş konforu arttırılabilir. Bu çalışma bir kasis üzerinden geçen araç için sistem davranışını ve sürücü konforunu incelemiştir. Kasis üzerinden geçiş hızları 5-25 km/sa arasında değerlendirilmiştir. Kasis uzunluğu TS 6283 standardına göre 3,6 m olarak alınmıştır. Kasis boyunun vücut ivmelenmesine etkisini karşılaştırmak için kasis uzunluğu 2,4 m olarak da alınmış, farklı kasis uzunlukları için sistem davranışı incelenmiştir. Hareket denklemleri Newton-Euler metodu kullanılarak çıkartılmış, Matlab-Simulink’te blok diyagramları oluşturulup simule edilmiştir. KareKök ortalaması (RMS) metodu kullanılarak ivme değerlerine göre Dikey eksende vücut ivmelenmesi ve yer değiştirmesi incelenmiştir.

The Effect of Bump Profile on Driving Comfort Using a Quarter Car Model with Passive Suspension System

Driving comfort is an important factor for driver health and safer driving. Depending on the road profile, driving comfort can be increased by reducing the in-vehicle body acceleration. This study examined system behavior and driver comfort for a vehicle passing over a bump. Passing speeds over the bump are evaluated between 5-25 km / h. The bump length is taken as 3,6 m according to TS 6283 standard. In order to compare the effect of bump length on body acceleration, the bump length was also taken as 2,4 m, and system behavior for different bump lengths was examined. Equations of motion were derived by using Newton-Euler method, block diagrams were created and simulated in Matlab-Simulink. Body acceleration and displacement on the vertical axis were investigated according to acceleration values using the Root Mean Square (RMS) method.
