Optimizatsiya tekhnologicheskogo protsessa sborki na rotornykh avtomatakh

The basic direction of promotion work is studying and optimization of technological process for automatic assembly by rotary assembly machines. In work for achievement of stated purpose the following problems have been solved: on the basis of the analysis of references examination of vibrating assembly methods which are used at various types of trajectories is carried out; at use of several criteria of optimization, the basic of which is the minimal time of existence of the detail axis in a field of a backlash the more optimal trajectory of moving of the assembled machine parts' axes in autosearch is established; the use of vibrations in the highly productive rotary assembly equipment is considered; is determined the influence of relative motion speed, forms of a trajectory, amplitude and frequency of fluctuations and of other factors on details assembling process and optimum variants of movement conditions for rotors and machine parts being assembled are considered; at a choice of friction forces on the contacting surfaces as the basic criterion of optimization is determined the optimum form of edges of the connected surfaces of details; is determined the influence of form and sizes of edges of the surfaces being joined on the allowable deviations of machine part's axes while using vibration methods; the influence of machine part misalignment in the positioning device on machine parts joining process is determined; the influence of forces on the details in the vibro-assembling process on details joining process, and the detail movement paths in the active zone are examined. For engineering calculations is proposed a calculating method of the vibrations mode of autosearch devices and are given nomograms for such autosearch devices. All listed above enables to provide a required level of economic efficiency of assembly process on rotary assembly machines. To the decision of the primary goal - optimization of technological process for assembly on rotary assembly machines it was applied two kinds of optimization: structural and parametrical optimization. At various design stages of technological process of assembly and a choice of the optimum decision various criteria of optimization were defined and some methods were used, namely: methods of analytical research, empirical methods and modeling. For computing experiments used personal computer IBM PC, programs "AutoCAD 2000', "Mathcad 8".Abstract in Latvian, English, Russian.
