On the damage mechanism of a cold rolling roll: Finite element analysis and material characterization

This paper presents a study of the mechanics of deformation of the four-roll pass cold rolling using an elastic-plastic finite element program. This process has been developed at the Anshan Institute of Iron and Steel Technology, People's Republic of China, where a new four-roll pass small section cold rolling mill has been built. The initial finite element analysis has been carried out for the rolling of 8 mm square section bar from 10 mm diameter round stock under dry friction conditions. The results show clearly how the areas of plastic deformation develop during the rolling process. The distributions of the generalized stress and the generalized plastic strain, both on the longitudinal symmetrical plane and on the transverse cross-sections of the workpiece, have been obtained, and the pressure distribution along the arc of contact has been determined. In addition, the roll separation force and the pass elongation of the workpiece predicted by the finite element program have been compared with the corresponding values measured in experiments when rolling 6.5 mm square section bar from 8 mm round material with machine oil lubrication. Good agreement has been obtained.

Beam Damage

The paper focuses on structural damage of cross beam arms for brake rod in the car of train. Analysis of cross beam was based on the design and actual conditions of the car application. Investigation the cross beam damage was done by finite element analysis. Based on the finite element analysis results, it is known that damage mechanism and design fault were caused by yield stress of cross beam that exceededthe material yield strength.Futher, a design improvement of cross beam was done by additional structure that can reduce the stress into safe limits.AbstrakRiset ini fokus pada kerusakan struktur batang lintang yang berfungsi untuk dudukan lengan rem pada kereta makan pada rangkaian kereta api. Analisa kerusakan batang lintang didasarkan pada kondisi desain dan kondisi aktual pemakaianya. Investigasi kerusakan batang lintang dilakukan dengan analisa finite elemen. Berdasarkan pada hasil analisa diketahui faktor penyebab dan mekanisme kerusakan pada batang lintang adalah akibat kesalahan desain yang menyebabkan tegangan melampaui tegangan yield material, selanjutnya dibuat perbaikan desain untuk kereta yang telah diproduksi dengan membuat struktur penguat sehingga tegangan yang terjadi turun pada batas aman.
