Simulation and modelling of rock breakage process by TBM rolling cutters in Abaqus

The tunnel boring machine (TBM) has been extensively adopted in tunneling constructions, due to its rapid advance rate, high efficiency, nice tunnel formation and little impact on the surrounding environment and security. The modern era of tunnel boring machines was born in the early 1950s. Since Robbins (1987) summarized the development and application of tunnel boring machines from the 1950s to the 1980s, various applications and models developed for tunnel boring machines have been received extensive attention in the last 30 years, such as application of shield method to urban tunneling ; application of multi-micro shield tunneling method to large rectangular cross-section tunnels, application of compact shield tunneling method to urban underground construction, application of a new hard rock TBM performance prediction model to project planning , and to blocky rock conditions  , application of a new method to predict the TBM performance in mixed-face ground for project planning and optimization , analysis of TBM performance in highly jointed rock masses and fault zones, and so on. The performance prediction and rock breakage mechanism by TBM cutters are becoming considerably important issues. Many experimental model were designed to predict the performance and to study the rock breakage mechanism of TBM cutters.

In this simulation cutter is modeled as three D rigid part and rock is modeled as deformable part. Appropriate material model is a important point to get the correct result in this simulation. You can see a figure of assemble parts at below

Dynamic explicit is a proper step for this type of analysis ans general contact interaction with erosion consider as input file. After the simulation the breakage of stone is obvious and you can see some figures of the results at below

You can provide CAE ,INP,and English video files of this simulation here. The cost of these files are Thirty Two US Dollars. you can click on the bellow bottom to beginning process

This is a important point when you want to select the payment port,select ROD PAY(this is a payment port for foreign buyers) and you can pay just with Bitcoins

If you haven’t Bitcoins You can pay it with PayPal or Master card just send me an email to this address:karampourp@gmail.com
