A Finite Element Approach to Investigate the Performance and Reliability of an Extension Stand in Table Saw Machines

Öz

e extension stand serves as an assistant to the single user on the table saw machine (TSM) without an inbuilt extension. This research developed and simulated an extension stand to estimate its performance reliability during operations. SOLIDWORKS software 2021 was used in designing the stand. Simulation and modelling of the components were performed with ANSYS 2021 to generate stress/strain analysis. The extension stand consists of medium wooden members (50 x 50 x 75 mm), having four (4) caster wheels at the upper part of the stand. The designed extension stand was fabricated and evaluated. The simulation analysis shows Maximum Directional Deformation at 3.889e-03 mm, Equivalent Elastic Strain at 2.667e-04 N/m^2, Stress and Yield Strength at 6.421e+06 N/m^2 and 3.930e+07 N/m^2 respectively, with the factor of safety at 6.1. The produced extension stand performed optimally with the estimated cost of manufacturing at N17,000.00 (US$38.04) as of 2021. The extension stand as evaluated passed the reliability test; it was strong enough to support the weight of the applied load during the empirical and simulated processes. The stand provides safety; it is affordable and easy to use.

Bir Uzatma Standının Masa Testere Makinelerindeki Performans ve Güvenilirliğini İncelemek İçin Sonlu Elemanlar Yaklaşımı

Öz

Uzatma standı, yerleşik bir uzatma parçası olmayan masa testere makinesindeki (TSM) tek kullanıcıya yardımcı olarak hizmet eder. Bu araştırma, uzatma standının operasyonlar sırasında performans güvenilirliğini tahmin etmek için bir uzatma standı geliştirdi ve simüle etti. Standın tasarımında SOLIDWORKS 2021 yazılımı kullanıldı. Bileşenlerin simülasyonu ve modellemesi, gerilim/şekil değiştirme analizini oluşturmak için ANSYS 2021 ile gerçekleştirildi. Uzatma standı, dört (4) tekerleğe sahip olan orta boy ahşap elemanlardan (50 x 50 x 75 mm) oluşur. Tasarlanan uzatma standı üretildi ve değerlendirildi. Simülasyon analizi, Maksimum Yön Deformasyonu olarak 3.889e-03 mm, Eşdeğer Elastik Şekil Değiştirme olarak 2.667e-04 N/m^2, Gerilim ve Akma Mukavemeti sırasıyla 6.421e+06 N/m^2 ve 3.930e+07 N/m^2 olarak göstermektedir ve güvenlik faktörü 6.1'dir. Üretilen uzatma standı, 2021 itibariyle üretim maliyeti N17,000.00 (US$38.04) olarak tahmin edilen optimal performans sergiledi. Değerlendirilen uzatma standı güvenilirlik testini geçti; ampirik ve simüle edilmiş süreçler sırasında uygulanan yükün ağırlığını desteklemek için yeterince güçlüydü. Stand, güvenlik sağlar; uygun fiyatlı ve kullanımı kolaydır.
