The topic of this paper is the design and numerical analysis of the obstacle removal mechanism that can be mounted on different vehicles for a special purpose. The introductory section will describe the role of special purpose vehicles in tasks that perform, and the role of the obstacle removal mechanism itself. The second chapter will discuss the conceptual elaboration of the whole mechanism and explain why such a mechanism is chosen and with what goals. The design will be elaborated in the third chapter. All parts of the mechanism will be listed and explained with all the necessary details. It will also show the tables of the selected standard parts used in the design of the mechanism. At the end od the chapter, the entire process will be presented in the simplified view of the punching process until the barrier is retracted. The fourth chapter will cover the finite element method that will be briefly described and the principles on which it is based will be outlined. Then there is a numerical analysis of the structure for puncturing and retraction. In both cases, the key parts of the strain will be analyzed. It will also reflect on the results of the analysis in a brief comment. Sixth and seventh chapters will encompass the selection of chains and hooks, and a manual calculation of the weld joints on the construction and that are also loaded during the punching process. A final conclusion has been made in the final chapter in which several parts of the paper are explained in more detail with further explanation of some parts of the paper. During the design the SolidWorks 2017 software package was used, and the for numerical analysis,Simulia Abaqsu 6.13.
