The paper is dedicated to the problem of design of the linkage mechanisms with large dwell of the output link in two positions. The research task is so important due to the fact that linkage mechanisms can be successfully used instead of other types of mechanisms with the dwell of the output link, in particular \u2013 cam mechanisms. The presence of the higher kinematic pair in cam mechanisms is the reason of limitation of their work velocities and force transmission conditions. Thus, the development of the methods of linkage mechanisms\u2019 kinematic synthesis in order to satisfy the given law of motion with the prescribed dwells is a topical scientific and engineering task. The basis of the proposed method is to search such geometrical parameters of the kinematic scheme of the basic four-bar linkage which provide the presence of two points of straightening in the coupler curve with high order of contact with the tangent line. It enables to obtain two long dwells of the output link if to join the basic mechanism with the structural group of the II class of 3rd<\/sup> type. It is established that to find the vector of variable parameters is sufficient to find coordinates of the self-intersection or mutual intersection points of special points\u2019 curves in the coordinate system which is linked to the coupler plane of mechanism. As a result of carried researches, the database of the synthesized mechanisms\u2019 geometrical and kinematic parameters is created. The appropriate software that enables to carry out the optimization procedure with prescribed conditions is also developed. The numerical example that is obtained by means of the developed methods is also given.
