Abstract

Purpose. Experimental study of the influence of fire trucks driving modes on the level of acceleration values occurring in tank structures under the action of inertial loads. To achieve the goal, the work included the selection of the necessary measuring equipment, determination of sensor installation locations and experimental conditions, processing of the obtained experimental data.

Methods. During the research, modern measuring equipment was used, including the Larson-Davis 2900 noise and vibration analyzer, piezoelectric accelerometers of type 352C18. The obtained experimental measurement results were processed using mathematical analysis methods totake into consideration measurement errors.

Findings. The experimental studies results of the acceleration’s general level occurring on the walls and bottom of tank structures under various modes of movement of fire trucks are presented. As a result of data processing, the dependencies were obtained linking the parameters (speed, acceleration, braking, turning) and conditions (type of road surface) characterizing the features of the modes of movement of fire trucks on the chassis of MAZ-5337 and MAZ-6317 with the values of acceleration arising under the action of inertial loads in tank structures having a volume of 5, 8 and 10 m3. The obtained maximum acceleration values, which range from 7.4 to 25.2 m/s2, indicate significant inertial loads occurring in tank structures and largely depend on the driving modes of fire trucks and the road surface. The data obtained confirm that fire tankers are operated in more severe conditions compared to other types of vehicles.

Application field of research. Firefighting rescue units, production and technical centers, industrial enterprises and higher educational institutions.
