Abstract
Dalam memenuhi kebutuhan proses industri, khususnya penerbangan dan industri pesawat luar angkasa, titanium tube menjadi bagian yang sangat penting. Untuk mengoptimalkan proses tube bending diperlukan pengertian lebih mendalam terhadap fenomena springback, agar hasil yang didapatkan lebih presisi. Pada penelitian ini dilakukan analisis springback menggunakan Finite Element Method dengan bantuan software ANSYS 15.0. Variasi yang digunakan pada penelitian ini yaitu sudut bending, ukuran sisi tube, dan ketebalan dinding tube. Diharapkan hasil permodelan ini dapat digunakan sebagai batu loncatan untuk penelitian berikutnya. Dari hasil penelitian didapatkan hasil bahwa springback terjadi setelah proses bending dan setelah pelepasan alat (remove tooling). Semakin besar sudut bending maka springback yang dihasilkan juga semakin besar, namun apabila ketebalan dinding tube bertambah besar maka springback yang dihasilkan bertambah kecil. Pengaruh ukuran sisi tube dan ketebalan dinding tube dapat dinyatakan dengan faktor geometri atau k. Semakin besar nilai k, maka semakin besar juga nilai springbacknya.
=================================================================
In meeting the needs of the process industry, especially the aviation and aerospace industry, titanium tubes become a very important part. To optimize the tube bending process required a deeper understanding of the springback phenomenon, in order to obtain more precise results. In this research, the springback is analyzed using the Finite Element Method with software ANSYS 15.0. Variations used in this research are the bending angle, size dimension of the tube, and tube wall thickness. Expected results of this modeling can be used as a springboard for the next study. Results of this research showed that springback occurred after the bending process and after the remove tooling. The greater the bending angle, the produced springback is also larger, but as the tube wall thickness grows, the springback decrease. The influence of size dimension of the tube and the tube wall thickness can be expressed by the geometry factor or k. The greater the value of k, the greater the springback value.
