Rationalization of material flow in production of semitrailer frame for automotive industry

Osnovna ideja rada je prikaz toka vrijednosti uz identifikaciju izvora troskova i nedostataka, koji ce pomoci da se razotkriju skrivene pricuve u proizvodnji. Analiza obuhvaca postojece stanje u pojedinacnim postupcima na proizvodnoj traci. Nakon prepoznavanja postojecih nedostataka napravljen je plan racionalizacije u kojemu je rabljena kombinacija elemenata lean proizvodnje. Predložena bi se rjesenja mogla primijeniti kad se primijene principi lean proizvodnje na pojedinim dijelovima montažne trake u cijelom pogonu. U slucaju da se predloženo rjesenje ne može primijeniti u praksi može se koristiti kao model za druge vrste poboljsanja kao sto su smanjenje otpada i nedostataka.

Study of Steel Wire Ropes Defects

This article deals with the study of defects in steel wire. In the study we model magnetic fields around rope genetated by magnetized part of rope. The work is based on the finite element program ANSYS. For the purposes of the experiments we consider one strand wire rope construction. We define different kinds of defects and faults. The shape of the magnetic induction lines of generated fields depends on the size of the defect, the depth of rope violation or the presence of other nearby defects. The location and number of disturbances have been chosen to achieve the most versatile outputs. All of these modifications were analyzed and the results displayed in the 3D colored.
