Abstract

This article discusses digital simulation and possible implementation of kinematic mechanisms and units on the basis of simple computational means (microprocessors). The proposed digital simulation is supported by geometrical plotting methods developed in descriptive geometry and successfully applied in engineering graphics. These methods, aided by compass, ruler, protractor and triangular ruler, make it possible to plot any trajectory, for instance, kinematic one. Technological basis of this simulation is a set of rapid algorithms based on integer arithmetic carried out by RISC microprocessors. Possibilities of this approach to designing of algorithmic support are exemplified by evolvent of circle. The obtained set of algorithms does not contain operations of multiplication and division; nevertheless, quite complex trajectories are obtained without trigonometric computations. The efficiency of the proposed procedure of algorithm designing is based on their fast operation, low cost of designing and simplicity of software implementation using microprocessors.
