Abstract
The paper shows that the adaptation of energy methods to automated calculation of mobile machines frame constructions consists of developing a single algorithm applicable to different construction schemes. The calculation outset still remains the idea of getting a function of potential energy of deformation as a function with unknown inner power factors. Search for local function minimum of potential power of deformation has been based on the function’s discrete grid-surface. We managed to reach tactical flexibility of coordinate descent method in an attempt to continue approaching local minimum in cases of a dead end situation by changing the discrete course. The paper suggests extending the implemented algorithm from 3-D surface dealing only with two power factors, to n-D one with many unknown values.
Highlights
Current trends in the engineering design of mobile machinery are closely linked to the development of computer technology and the emergence of new universal applications
Computational models which can significantly accelerate the processes of the most complex calculations are widely used. Such models are especially successfully applied in calculations to determine the stress-strain state (SSS) of complex structural structures
In the current practice of designing mobile machines frames, there is a significant share of manual operations in calculating their strength, associated with the Adaptation of Energy Methods to Automated Calculation
Summary
Current trends in the engineering design of mobile machinery are closely linked to the development of computer technology and the emergence of new universal applications. One of the most loaded elements of mobile machinery is the frame, which is a spatial load-bearing metal structure and consists of numerous closed contours. In each such contour at an arbitrary external load, there are six internal force factors, the determination of which from the static equations becomes impossible. The use of modern automated methods for calculating the frame structures of mobile machines will significantly accelerate the process of their design as well as increase the reliability of the machine through a reasonable choice of the optimal version of the bearing system. The developed methods can be designed in the form of application packages with their subsequent implementation in CAD for the calculation and analysis of the load of frame structures
