Biomimetic Based Design and Analysis of Vehicle Seat Back Support

Öz

Although automotive manufacturers realise vehicle and upholstery designs by considering the body integrity of their potential customers, the existence of certain pains in the human body can't be prevented in various situations. Despite different methods and tools are used to solve the problem of back pain from various pains, complete solution can't be provided. With this target, a back support design which is shaped according to the person's body ergonomics has been realized with the biomimetic design lens approach, absorbs the load acting on the waist and back contact surfaces depending on the weight of the person and offer comfort above standard. Various solutions found in nature were examined and it was decided to use the spine form in the targeted design, since hedgehog spines have high impact absorbing properties. In this context, the design made with 3 different action scenarios and the back support design used in present were compared. In addition, the design was analyzed ergonomically using the REBA method. While performing the analysis studies, recyclable thermoplastic elastomer hydrogel material was preferred for spines. Consequently, it has been understood that the proposed design will be a more positive alternative compared to the existing designs.

Araç Koltuğu Sırt Desteğinin Biyomimetik Tabanlı Tasarımı ve Analizi

Öz

Otomotiv üreticileri potansiyel müşterilerinin vücut bütünlüğünü göz önüne alarak araç ve döşeme tasarımlarını gerçekleştirmelerine rağmen çeşitli durumlarda insan bedeninde bir takım ağrıların oluşumu engellenememektedir. Oluşan çeşitli ağrılardan sırt ağrısı problemini çözmek için farklı yöntem ve araçlar kullanılsa da tam anlamı ile bir çözüm sağlanamamaktadır. Bu hedefle biyomimetik tasarım lensi yaklaşımı ile kişi vücut ergonomisine göre şekil alan, bel ve sırt temas yüzeylerine kişinin kilosuna bağlı olarak etki eden yükü absorbe eden standardın üzerinde bir konfor sunacak sırt desteği tasarımı gerçekleştirilmiştir. Doğada bulunan çeşitli çözümler incelenmiş ve kirpi dikenlerinin yüksek darbe sönümleme özelliğine sahip olması sebebiyle hedeflenen tasarımda diken formundan yararlanılmasına karar verilmiştir. Bu kapsamda 3 farklı eylem senaryosu ile yapılan tasarım ve mevcutta kullanılan sırt desteği tasarımı karşılaştırılmıştır. Ayrıca tasarım REBA yöntemi kullanılarak ergonomik açıdan da analiz edilmiştir. Analiz çalışmaları gerçekleştirilirken dikenlerde geri dönüştürülebilir termoplastik elastomer hidrojel malzemesi tercih edilmiştir. Sonuç olarak ortaya konan tasarımın mevcut tasarımlara oranla daha olumlu bir alternatif olacağı anlaşılmıştır.
