The actual problem of the strength properties evaluation of a special armored vehicle "NOVATOR" designed for the transportation of personnel and special cargo is considered. When an armored vehicle roll-over, the strength of the capsule must ensure the preservation of living space for the crew.
To evaluate the strength of the capsule when vehicle rolls-over, in the program Solid Works a spatial model of the fabricated hull of the armored capsule, taking into account the materials of all parts, was developed. Calculations of the stress-strain condition of the capsule and its frame are performed. To analyze the stress-strain condition of the armored vehicle capsule due to static and dynamic loads the finite element method was used, which is implemented in the program SolidWorks Simulation. Simulation of the structural strength by different types of loads was performed in order to adequately evaluate the strength of the capsule.
The results of calculations and simulation of the capsule design showed its insufficient strength, which can lead to significant spatial deformations of the capsule hull and the threat to human life. It does not meet the requirements of UNECE Regulation №66 for motor vehicles to transport people in terms of the strength of their superstructure.
To ensure the required strength of the capsule the analysis of design flaws was performed. The main causes of strength loss and location of critical stresses and strains by sensing the model are identified.
Recommendations were given to the manufacturer to increase the strength of the capsule and provide the necessary safety margin of the structure.
