The paper presents the results of the conducted tests of torsional stiffness of the VOSCO S106 passenger car, as well as the validation process of these tests by means of numerical analyzes using the FEM finite element method. The most important element of the vehicle structure is the part of the spatial frame or the safety cage. Engine, brake system, fuel system and steering system, suspension as well as body and parts, their mounting nodes, hinges, locks, etc. are attached to the frame. The frame must therefore have adequate strength to protect the driver in the event of a tipover or impact. The frame is usually made of steel pipes with the prescribed dimensions and strength according to regulations. The torsional stiffness of the vehicle chassis has a significant influence on its driveability and therefore is an important parameter to measure. In this article, the torsional stiffness of the vehicle frame is calculated experimentally, which was then verified by finite element analysis (FEM) using the Altair HyperWorks program.

The following article presents fatigue testing and FEM numerical analysis of an autonomous electric vehicle, PAWO autonomous operational support platform. The purpose of the study, which was carried out in the ŁUKASIEWICZ – Automotive Industry Institute, was to verify the structure of the platform by forcing in three axes on the position: a table with six degrees of freedom "MAST", as well as conducting fatigue numerical analyses, allowing to determine places critical for fatigue endurance. This will be the starting point for the modification of the structure, and also will allow you to identify places that you need to pay attention to during tests and subsequent operation. The results of these tests allow us to determine critical places due to fatigue strength and possible intervention before starting field tests with a complete vehicle, as well as to detect places that should be noted during tests, inspections and tests, and in development versions of the vehicle.
