Cabin Safety Prediction in a Selected Group of Mobile Working Machines

Abstract

Protective structures are safety constructions fitted to self-propelled earth moving machinery providing reasonable accident protection for the vehicle operator in the driving position. Verification and certification of the proposed solutions is an important step in the development process or the innovation process of new constructions of mobile working machines. These processes are regulated by valid regulations and standards. They are run in standard conditions, also in the form of destructive tests on fully functional modules. In case of deficiencies, these processes must be rerun on new modules, resulting in additional financial cost. The paper deals with simulation of the required tests with attention to time saving and reducing financial cost. The simulation aims to streamline the design process of the machine or its modules. It has been proven that it is possible to accurately simulate destructive tests of cabins for working machines. The results of a simulation and real destruction tests of the cabin were compared by deformation graphs.
