ÇEŞİTLİ ESNEK ATALET ARTIRIMI MEKANİZMALARININ PERİYODİK TİTREŞİM YALITICISI TASARIMINA YÖNELİK PARAMETRİK İNCELEMESİ

Abstract

Bu çalışmada, iç içe gömülmüş atalet artırımı mekanizmalarıyla oluşturulmuş bir periyodik yapı, titreşim yalıtıcısı olarak tasarlanmıştır. İlk olarak, çeşitli esnek atalaet artırımı mekanizma konfigürasyonları önerilmiştir. Yapılan parametrik çalışmalar neticesinde, bu mekanizmalardan en geniş titreşim yalıtımı frekans aralığına sahip olanı belirlenmiştir. Ardından, bu seçilen tasarım, periyodik yapının birim hücresi (yani, periyodik yapıda tekrar eden yapı bloğu) olarak kullanılmıştır. Son olarak, periyodik yapının titreşim yalıtımı performansını göstermek için deplasman iletkenliği (yani, frekans cevap fonksiyonu) grafikleri sunulmuştur.

A PARAMETRIC INVESTIGATION ON VARIOUS COMPLIANT INERTIAL AMPLIFICATION MECHANISMS FOR A PERIODIC VIBRATION ISOLATOR DESIGN

Abstract

In this study, a vibration isolator is designed as a periodic structure, which is constructed with embedded inertial amplification mechanisms. At first, various compliant inertial amplification mechanism configurations are proposed. Among them, the one with the widest vibration isolation frequency band is selected via conducted parametric studies. Then, the determined mechanism is utilized as the unit cell (i.e., the repetitive building block) of the periodic structure. Finally, the displacement transmissibility (i.e., Frequency Response Function (FRF)) plots are presented to demonstrate the vibration isolation performance of the designed periodic structure.

Keywords

• Parametric study
• compliant mechanism
• vibration isolation
