Abstract

Bu araştırma, kullanıcıların yaşam kalitesini iyileştirmeyi hedefleyen sürdürülebilir diz eksartikülasyon protezlerini kişiselleştirebilmek adına yenilikçi bir hesaplama metodolojisi önermektedir. MATLAB ile kinematik denklemlerin çözümünü, Solidworks ile hareket analizini ve ANSYS Workbench ile malzeme ve statik analizleri gerçekleştirecek şekilde özel bir hesaplama tekniği formüle edilmiştir. Bu araçların bütünleştirilmesi, tasarım ve analitik sonuçların doğrulanmasını mümkün kılmıştır. Kinematik çözümler, bireyin ve protezin ağırlıklarını dikkate alarak, protezin işlevselliğine uygun hareket aralığında lineer ve açısal dinamikleri incelemiştir. Protezin üzerindeki maksimum kuvvet etkisini belirlemek amacıyla statik analiz gerçekleştirilmiştir. Araştırmanın bulguları, 20 ile 80 yaşları arasında, 160-190 cm boy ve 80-120 kg ağırlık aralığında olan bireyler için en uygun protez özelliklerinin tespit edilmesine katkı sağlamıştır. Protez tasarımı, koşma ve zıplama gibi geniş bir hareket aralığı gerektiren aktivitelerde hareket serbestliğini desteklemiştir. Protez, vücut hareketlerine çabucak adapte olmuş ve yaklaşık üç saniye içinde kullanıma hazır duruma gelmiştir. Bu çalışma, protez tasarımının anatomik ve kinematik açılardan en iyi şekilde optimize edilmesi için mühendislik ve tıp disiplinleri arasındaki iş birliğinin kritik önemini vurgulamaktadır.

DEVELOPMENT OF A METHOD FOR CALCULATING LOADS ON IMPLANTS AND PROSTHESES USED FOR THE HUMAN SKELETON

Abstract

The study proposes a novel computational approach for customizing sustainable knee disarticulation prostheses, aimed at improving the quality of life for users. A specialized calculation technique for assessing the loads and moments on the prosthesis was formulated, leveraging MATLAB for solving kinematic equations, Solidworks for motion analysis, and ANSYS Workbench for material and static analysis. The integration of these tools enabled the validation of the design and analytical outcomes. The kinematic solutions accounted for individual and prosthesis weights, analyzing linear and angular dynamics over a motion range pertinent to the prosthetic leg's function. Static analysis was executed to determine maximum force impact on the prosthesis. The study's results were conducive to identifying the most suitable prosthesis characteristics for individuals aged 20 to 80, with a height of 160-190 cm and a weight of 80-120 kg. The prosthetic design promoted ease of movement in activities requiring a range of motion, such as running and jumping. The prosthesis adapted swiftly to body movements, achieving readiness in approximately three seconds. The research underscores the importance of interdisciplinary collaboration between engineers and medical professionals to optimize the anatomical and kinematic aspects of prosthesis design.
