Finite Element Analysis of wire ropes made big influence on researchers
last decade. Requirement of an correct 3D wire rope model is the most important
issue during analysis. To accomplish such a good model with error free surface
representation for helical wires are mostly very difficult even sometimes
impossible for some kind of helical shapes. This paper aims to show how to
construct such an complicated wire rope model. For this purpose parametric
mathematical equations of the single, double and triple wire models are
represented. Proposed triple helical wire rope model is constructed by using a
code instead of ready use commercial 3D software for material design. The
constructed model can be adopted to any analysis tool to find numerical
results.

Tel halatlarla ilgili yapılan Sonlu Eleman Analiz çalışmaları
araştırmacılar arasında son on yılda büyük ilgi uyandırmıştır. Analiz
çalışmaları sırasında doğru üç boyutlu tel halat modelleri ihtiyacı en önemli
gerekliliktir. Böyle yüzey hatalarından arındırılmış bazı helisel şekillerin
bir katı modelini oluşturmayı başarmak çoğunlukla çok zor hatta bazı zamanlar
imkansız olmaktadır. Makalenin amacı bu tür karmaşık bir tel halat modelinin
oluşturulmasını göstermeye çalışmaktır. Bu amaçla tekli, ikili ve üçlü tel
halat modellerine ait parametrik matematik denklemler gösterilmiştir. Önerilen
üçlü helisel halat modeli tasarımı hazır üç boyutlu tasarım uygulamaları kullanılmadan,
özgün olarak geliştirilmiş bir kod yardımıyla oluşturulmaktadır. Tasarlanan
model herhangi bir analiz aracına uyumlu hale getirilerek sayısal çözümler elde
edilebilir.
