The issue of mechanization of hanging of long components of self-installing rock bolt (SIRB) type has been considered. The possibility of usage of slider-crank mechanism for these purposes has been proved. Linear dimensions of lever mechanism that meet the requirements defined by the applied motor and SIRB parameters have been determined on the ground of parametric synthesis. The performed force analysis has proved the application of fluid power drive.

In a number of engineering problems in the development of automated systems arises a necessity in the computation and design of a fluid power drive (FPD) in conformity with particular technological schemes for which there are no finished industrial products or it is necessary to carry out a sufficiently exact correspondence of operating characteristics with specified engineering data. In this case one does not carry out the selection of standard elements for a fluid power drive, but performs their designing, where there were used modern approaches and methods of the computeraided design. As operation results show, a designed fluid power drive in most cases cannot possess required for system functioning dynamic properties: performance, capacity for a decrement, sensitivity and so on. According to the investigations, they depend in many respects upon such characteristics of a hydrosystem as static fluid of a hydrocylinder and piping, time constant of transient and damping coefficient. If we consider the process of FPD designing as a procedure of a parametric synthesis, then the research of its variants with different combinations of parameter values gives a possibility not only to choose geometrical dimensions for a unit, but to estimate its potential operational functionalities. At present time as one of the effective approaches in the realization of such a solution may be the application of methods for the evolutionary simulation, where each object analyzed is considered as an individual. As an example of the evolutionary simulation there are considered the results of FPD servicing characteristics estimate computed on bases of design data for a forklift truck. The graphic dependences obtained establish the extreme correlations of hydraulic actuator operational characteristics which stipulate for a stable work of the fluid power drive in the transient behavior without special damping devices. Results of the evolutionary simulation allow analyzing the influence of parameters mentioned upon the damping coefficient changes and drawing a conclusion for decision making for the choice of such a design variant of a fluid power drive at which there would be ensured the best servicing characteristics of the plant.

Power Drive

Problem. The hydraulic drive of modern construction and road machines is quite complex, and it takes a lot of time and effort to model the entire drive in full. However, improving the quality of design with reducing terms and costs becomes possible only with the use of modern technologies, computer hardware and software. The existing models of hydraulic system working processes in the physical modeling environment SimHydraulics are presented by block diagram layouts from standard library elements (slide valve, hydraulic pump, hydraulic cylinder, safety and reverse valves, hydraulic locks, etc.). However, they do not consider the influence of time-varying external forces, which are a reaction during transient processes in multi-link mechanical systems. Goal. The aim of the work is to develop a simulation model of the fluid power drive of the excavator working equipment mechanical system in the MATLAB & SimHydraulics package for studying the dynamics of transient processes of multilink mechanical objects. Methodology. The article describes an example of developing a physical simulation model of the excavator working equipment fluid power drive in the SimHydraulics package. Using the real technical characteristics of the hydraulic equipment of the Borex 2201 excavator, the performance of the developed model was checked and the power characteristics of the actuators were determined. Originality. Using the blocks described in the article, a simulation model of the interaction of the excavator working equipment mechanical system with its fluid power drive can be created. Practical value. The model proposed makes it possible to obtain values characterizing transient processes, including changes in the value of the generalized coordinates of the characteristic points in the working equipment, the rate of their change, and the effort in the hydraulic cylinder. A visual representation of the manipulator movement can be obtained using the SimScape built-in visualization function. The resulting model allows solving problems of analysis and synthesis of excavator operation control systems.
