Most of the arm lifts used in today’s industry are designed and manufactured based on the scissor mechanism. Such schemes have one drawback: when the mechanism is raised, their connection points with the base and the movable platform narrow, which leads to a let-down in its stability. This article proposes a new scheme for the lifting device, which eliminates the above disadvantage of scissor schemes. In the scheme developed by the authors, the joints connecting the mechanism to the moving platform and the base are fixed, which means that the distance between the connection points does not change, leading to its stable operation. The mechanism consists of one group of links of the second class and two groups of links of the fourth class. The article focuses on the stability of an automotive lift’s design when moving with a load. The article presents the results of a kinematic and kinetostatic analysis, a study of the stability of the lift and the results of studies of an experimental sample of the developed lift. The methods presented in this article allow for the design of automotive lifts with new lever mechanisms, as demonstrated by computer modeling and experiments.

“…Foremost, researchers consider the synthesis of crank presses in other settings, particularly the synthesis of a crank press based on a more complex structure or to ensure the working link's dwell [8][9][10][11]. Defined work [8] considers the solution to this task at the expense of control, for which additional latitude is introduced into the kinematic chain; they are called hybrid press systems.…”

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.

“…Halicioglu proposes a modeling and design method for a crank servo press based on Lagrangian [14]. In [15,16], the SimulationX software package was used in dynamic modelling of a servo mechanical press. Dynamic model of the servo mechanical press was composed with account for elastic-dissipative characteristics of the links and the parameters of the servomotor [15].…”

High mechanical advantage as well as low and steady slide speed within the working stroke Sn are the fundamental requirements for the working mechanism of servo-mechanical press. Currently, the Crank-Triangular Linkage-Elbow (CTLE) mechanism has attracted more and more attention from researchers and manufacturers of servo presses. This paper presents a new analysis and design method of CTLE. The mechanism is decomposed into two sub-units: crank and triangular-linkage elbow, followed by the kinematic and force analysis of each sub-unit. The influences of each structural parameter on the working performance are obtained and can be used as the basis for preliminary design. Through the offset design, the mechanical advantage peaks of the two units, MA1max and MA2max, do not occur at the same time: MA1max is located near Sn, while MA2max is just at BDC (Bottom Dead Center). Because the mechanical advantage of the whole mechanism is the product of the two subunits, the designed mechanism can obtain high and steady mechanical advantage together with low and steady slide speed within Sn. After preliminary design, the scheme can be further modified by numerical simulation and optimization. Hence the design efficiency can be improved.
