Abstract

Purpose. Modernization of operating fire trucks' tanks in order to increase operational reliability and to enhance the turnaround period.

Methods. The research was carried out using the ANSYS software package.

Findings. The estimated finite element models of tanks have been developed. They allow recognizing the nature of the liquid dynamic impact on the walls under various modes of firefighting engine movement, predicting the places of probable structural failure and justifying changes in the structure. The dependences of the geometric parameters influence of tank elements on its stress-strain state and strength properties during operation are established. The results of the theoretical substantiation of the optimal effectiveness of stiffeners usage (according to the criteria of construction safety margin, amount, size, location) in the tank structure are presented. Application field of the research. The results of the research can be applied in the design of new and modernization of existing tanks for the transportation of liquid cargo by road.
