Abstract

The use of modern computer technologies makes it possible to achieve high practical and economic results in various fields of industry. Information technologies used in design are also actively developing. There is an increasing number of various computer simulation programs. The article proposes a 3D model of the structure of a metal subframe with subsequent calculation of the loads acting on it in the ANSYS Workbench 16.2 software package using the Static Structural module. Loading diagrams are given and graphs of the movement of the structural unit under study are formed for four cases of movement of airfield special equipment. An analysis was made of the dynamic characteristics of the movement of the car and the coefficients of adhesion to the road, during which the numerical values suitable for the developed system were determined in order to calculate the contact and non-contact forces. In the course of research, for each type of movement, the numerical values of the loads along the three main axes were identified. Dangerous areas are indicated where cases of violation of the integrity of the structure are possible. On the basis of the data obtained, a conclusion was formed that allows developing the design of an airfield watering machine, while eliminating shortcomings and errors in the design of power units of equipment.
