Simulation of the pipe bending process using three rollers Abaqus

Project Overview

In this example, we simulate the pipe bending process using three rollers in the Abaqus software.

The pipe is made of Copper, while the three rollers are modeled as rigid parts. The rollers rotate with an angular velocity of 0.5 radian per second to bend the pipe.

The pipe has a total length of 70 cm and undergoes bending as it comes into contact with the three rotating rollers.

Pipe Bending Process

In a three-roller pipe bending process, the pipe is positioned between three rollers. As the rollers rotate and apply contact forces to the pipe, the pipe undergoes gradual bending deformation.

The rollers guide the pipe and apply the required forces through contact interaction. As the pipe moves through the rollers, it changes from its initial straight configuration to a curved configuration. The amount of bending depends on the roller arrangement, roller motion, and mechanical properties of the pipe.

Dynamic Explicit Analysis

Two Dynamic Explicit steps are used to simulate the pipe bending process. This analysis method is suitable for modeling the large deformation and contact between the Copper pipe and the rigid rollers.
