Static and dynamic analysis of telescopic boom of self-propelled tunnelling machine

Damian Derlukiewicz, Jacek Karliński
The paper presents selected aspects of the strength analysis of the self-propelled tunnelling machine boom. The principles of creating calculation models for numerical simulations with use of the finite element method are given. The study also presents two ways of conducting numerical calculations in both the static and dynamic range. A detailed example of numerical FEM tests of the telescopic boom is provided.
