Trans Motauto World, Vol. 2 (2017), Issue 2, pg(s) 83-86

Based on the analysis of the mathematical model of the motor grader movement in the process of implementation of working operations, the factors that have the greatest influence on formation of the machine’s motion path are identified. It is proved that some of the factors characterizing the parameters of the machine and technological process have a destabilizing impact on the formation of the grader motion path, while the rest of them have a stabilizing impact. The analytical research enables developing practical recommendations to ensure the movement of the machine along a predetermined path without deviations.

A major part of working operations performed by a motor-grader is accompanied by asymmetric action of the resultant vector of external resistance forces applied to the main blade. The eccentrically applied horizontal loads together with additional lateral forces affect the parameters of the machine road-holding ability resulting in deviation of its actual trajectory from the planned one. In the presented work on the basis of the developed model there have been analyzed the impact of operational characteristics of the working process on the indicators of the machine road-holding ability.

• ## METHODS TO DETERMINE MEASURES PROVIDING A MOTOR-GRADER ROAD-HOLDING ABILITY

Performance of work operations by a motor-grader is accompanied by action of asymmetrically applied external loading. As dissipative forces act between the wheels and the support surface, this force action leads to the grader deviation from the set trajectory of movement. The experimentally developed model of the vehicle behavior at performing work operations allows estimating indexes of road- holding ability depending on soil characteristics, geometric and kinematic parameters of the machine.

Direct Metal Laser Sintering (DMLS) is a revolutionary technology that allows a production of fully functional metal parts directly from a 3D CAD data, eliminating the investment to production tools and technologies which brings considerable cost and time savings. Metal parts made by DMLS technology are fully comparable with casted or machined parts. A range of application of DMLS technologies is very wide – from prototypes, through short-run production to final products. Advantages of DMLS technology are arising along with complexity of parts – more complex geometry of parts (in terms of shape and occurrence of the detail) make DMLS technology even more economically effective.
