Abstract
In this study, a vibration fixture capable of testing larger and heavier structures during vibration tests was designed. The aim was to enable the execution of vibration tests by driving the system with a single shaker in cases where the dual shaker system could not operate synchronously. The brackets and connection plates of the designed fixture were manufactured using Al 6061 series aluminum material. For the linear motion system, the SRG 65 LC model from THK was selected. The fixture design was created using CATIA software, while the modal and dynamic analyses were performed using ANSYS software. The analyses were conducted within a frequency range of 5–100 Hz and a vibration profile of 0.25g magnitude. According to the results of the modal analysis, the natural frequency of the fixture along the X-axis was increased above 100 Hz. This ensured that the natural frequency was higher than the vibration profile frequency range, effectively preventing resonance. Consequently, vibration-induced energy was successfully transmitted. Following the analyses, the fixture was manufactured and mounted on the shaker along the X-axis for experimental testing. Data collected from accelerometers indicated that the vibration energy was transmitted smoothly.

Abstract
Bu çalışmada, titreşim testlerinde daha büyük boyutlu ve ağır yapıların test edilmesine olanak sağlayan bir titreşim fikstürü tasarlanmıştır. Özellikle çift sarsıcı sisteminde sarsıcıların senkron çalışamadığı durumlarda, tek bir sarsıcıdan tahrik verilerek titreşim testlerinin gerçekleştirilmesi hedeflenmiştir. Tasarımda kullanılan fikstürün braketleri ve bağlantı plakaları, Al 6061 serisi alüminyum malzemeden üretilmiştir. Lineer hareket sistemi için ise THK firmasına ait SRG 65 LC modeli tercih edilmiştir. Fikstürün tasarımı, CATIA yazılımı ile yapılmış, modal ve dinamik analizleri ise ANSYS yazılımı kullanılarak gerçekleştirilmiştir. Analizler, 5-100 Hz frekans aralığında ve 0.25g büyüklüğündeki bir titreşim profili üzerinden yapılmıştır. Modal analiz sonuçlarına göre fikstürün X eksenindeki doğal frekansı 100 Hz’in üzerine çıkarılmış, böylece titreşim profili frekans aralığından daha yüksek bir değere ulaşılmış ve rezonans etkili bir şekilde önlenmiştir. Bu sayede titreşim kaynaklı enerji başarılı bir şekilde aktarılmıştır. Analiz sonuçlarının ardından fikstür üretilmiş ve X ekseninde sarsıcıya monte edilerek deneysel testler gerçekleştirilmiştir. İvme ölçerlerden alınan verilerin titreşim enerjisini düzgün bir şekilde ilettiği gözlemlenmiştir.
