Purpose. Calculation of the stress state and safety margin of modern 5 m3 tank’s construction of fire trucks made of composite materials and high-alloy steel considering operational loads.
Methods. The development of 3D-models of tank structures was carried out using the SolidWorks software package. The creation of their finite element models and calculations were carried out in the Static Stractural module of the ANSYS Workbench software package.
Findings. The analysis of the composite materials’ features utilization in the modern production of fire trucks is carried out. Their advantages in comparison with steel ones are presented. 3D finite element models of 5 m3 tank structures made of reinforced fibrous fiberglass and high-alloy stainless steel have been developed. To carry out a comparative calculation, the most loaded modes and conditions characterizing the features of the movement of fire trucks moving to emergency response place were selected. The calculation made it possible to establish dependencies linking the stressed state of tank structures with the modes of movement of fire trucks, as well as to identify the most loaded nodes in the structures. The results of calculating the safety margin of tank structures considering operational loads are presented.
Application field of research. Firefighting rescue units, industrial enterprises and higher educational institutions.
