Abstract. In this paper we consider the formulation and solution of the task of a dynamic synthesis machine with an asynchronous electric motor and a slider-crank mechanism. The constant parameters of the slider-crank mechanism (mass and moments of inertia and centers of gravity of links) and the parameters of the electrical motor are defined. The laws of motion of the machine and kinematic parameters of the mechanism are considered as given. We have developed the method of optimal dynamic synthesis of the machine, which consists of an asynchronous electric motor and a slider-crank mechanism. The criterion of optimization of the dynamic synthesis of a machine is the root mean square sum of the moments of driving forces, the forces of resistance and inertia forces which are reduced to the axis of rotation of the crank. The method of optimal dynamic synthesis of a machine can be used in the design of new and the improvement of known mechanisms and machines.

The design of any mechanism begins with the design of its scheme. Subsequent calculations for strength, structural design of links and kinematic pairs, choice of materials, and other stages of the design, as a rule cannot significantly change the basic properties of the mechanism. The design of mechanisms scheme on the specified properties is called synthesis of mechanism. In this work we considered the software package of kinematic synthesis of spatial gear lever mechanisms for five, seven, eight and nine parameters.

In this article present a new method for investigating the functionality of the crank-slider mechanism for a given coefficient of change in the average speed of the slider and the optimal transmission angle to ensure the most outstanding transfer of force from the input link to the working element (output link). When implementing the technological process оn crank presses, it is necessary to provide a predetermined working cycle of the slider motion: fast lifting, dwell and slow lowering. This mechanism allows for a slow lowering of the working link in the load phase and a fast lifting in the unloading phase of the crank press's working body. Based on the above method developed a program in the Delphi 7 visual system. Delphi 7 allows you to quickly and easily develop effective applications, including database applications. The system has advanced capabilities for creating a user interface, a wide range of functions, methods and properties for solving applied computational problems. The system has advanced debugging tools that facilitate the development of applications, which allows determining the parameters of the synthesized crank-slider mechanism by the optimal pressure angle and conducting a kinematic analysis of the movement of the links in the dialogue mode.
