Elements of Dynamics of Machines with Program Control

Abstract

In modern machine building two methods are applied for designing program motions of working organs of a machine necessary for the fulfillment of specified working processes. The first method which is widely used for single-engine cycle machines consists in feeding the engine input with an input signal ensuring a nearly uniform rotation at the output of a rotor engine or a periodically reciprocating motion (in a linear engine). The transformation of these simplest motions into desired program motions of working organs is carried out by actuating mechanisms (lever-, cam-, gear- and other ones) which have, as a rule, nonlinear position functions. One might say that programming mechanisms are applied in such machines.
