Abstract

The aim of this study is to determine and compare the torsional stiffnesses of the revolute compliant joints that are made of thermoplastic polyurethane (TPU) material. By setting up a sensitive measurement system, tilt angles were measured at different loading values for four samples and the reaction moments are determined to calculate experimental torsional stiffness. The results of the theoretical model based on a cantilever plate model is in general compatible with the experimental results. The effect of the compliant hinge geometric parameters on the results are discussed. It is concluded that the proposed experimental setup can be used effectively in the measurement of the torsional stiffness of revolute compliant joints.

Özet

Bu çalışmanın amacı, termoplastik poliüretan (TPU) malzemesinden üretilmiş olan ve kendi rotasyon ekseninde dönebilen mekanizma parçalarının torsiyonel direngenlik sabitlerinin deneysel ve teorik olarak elde edilip karşılaştırılmasıdır. Hassas bir ölçüm sistemi kurularak dört numune için farklı yüklerde eğilme açıları ölçülmüş ve tepki momenti değerleri belirlenmiş, böylece deneysel torsiyonel direngenlikler hesaplanmıştır. Ankastre levha kullanılarak elde edilen teorik model ile deneysel sonuçların genel itibariyle uyumlu olduğu kaydedilmiştir. Dönme mafsalı boğaz bölgesi geometrik parametrelerinin sonucu ne şekilde etkilediği tartışılmıştır. Önerilen deney düzeneğinin dönme mafsalı torsiyonel direngenlik ölçümünde etkin bir şekilde kullanılabileceği sonucuna varılmıştır.
