Abstract:

Purpose. Automation of the process of designing the profile of gas distribution mechanisms (GDM) of internal combustion engines of all types, ensuring the reliability and durability of their operation.

Methodology. The speed and acceleration of the GDM pusher were determined by applying discrete differentiation. This enabled forming a differential band of values of the first and second separated differences of the original coordinates of the pusher’s movement schedule on the basis of which the average speed and acceleration graphs of the GDM pusher were constructed. The SolidWorks CAD system was used to automate computer simulation of the cams’ functional surfaces to obtain a 3D model of the camshaft, which can provide the required accuracy.

Findings. In order to form plane contours of the GDM functional surfaces of internal combustion engines, which are given with the necessary accuracy, the authors propose algorithms for obtaining linear elements of computer models of the projected surfaces. The proposed method was tested using CAD to optimize the geometric shape of the cam to obtain a computer model of the camshaft in order to increase the performance of the GDM of the internal combustion engine.

Originality. The original method is provided for determining the values of speeds and accelerations of the GDM pusher’s motions of internal combustion engine, which is based on constructing a band of differential projections of the first and second separated differences of the values of its movement coordinates. This method ensures the absence of oscillation of the obtained speed and acceleration graphs of the pusher’s movement by determining the values at the beginning and end points of the graph, which was not possible by using the traditional method.

Practical value. The methodology of automated design of the working surfaces of distribution shafts of all types with ensuring reliability and durability of their operation has been developed.

Keywords: internal combustion engine, distribution shaft, pusher, cam, discrete differentiation, separated differences
