The paper presents the results of the tests of strength and torsional stiffness of the PAWO autonomous high mobility vehicle frame, using numerical analyses using the FEM finite element method, as well as energy storage (battery) strength analyses in accordance with UNECE Regulation No. 100. The most important element of the vehicle structure is part of the space frame or safety cage. The engine, braking system, fuel system and steering system, suspension, as well as the body and parts, their assembly knots, hinges, locks, etc. are attached to the frame. The frame must therefore be of sufficient strength to protect the structure and the load in the event of overturning or impact. The frame is made of steel pipes of specific dimensions, and strength is determined by regulatory requirements. The torsional stiffness of the vehicle chassis has a significant impact on its driving characteristics and is therefore an important parameter for measurement. Energy storage (battery) testing is of great importance from the point of view of the safe operation of an electric vehicle.
