Analysis of the eigenfrequencies of the basalt machine parts by the FEM
2021
The aim of this paper was to carry out a theoretical (numerical) scientific research on the behavior of cast and recrystallized basalt, in order to use it as a material in the manufacture of structural elements of machine tools. A unitary methodology has been established for studying the eigenfrequency of structural elements for machine tools by the finite element method. Two basalt structural elements (beam type and plate type) were modeled, which were also made physically, and with the help of the COSMOS / Mark finite element program, the eigenfrequencies of the models was studied.
Study on Experimental Determination of the Elasticity Modulus of Casted Basalt
2020
Basalt is a material available in big quantities in nature. It has a low price and can be used in various domains. It can be relatively easily extracted from natural deposits and processed by means of melting. Melted and recrystallized basalt has demonstrated promising behavior with regards of its use in manufacturing, as reported in the literature. This paper presents the results of an experimental study on the determination of the modulus of elasticity of molten and recrystallized basalt by the method of resistive electrical tensometry and to validate the result and by simulation using finite elements method. Testing methodology, experimental test, data records, data processing and result…

Consideration Regarding the Configuration of the Resources and Modeling the Manufacturing Work Cell
2015
This paper is presented the concept of developing a generic reference architecture model for the specification, development, control and reconfiguration of a manufacturing enterprise at a work cell level. It is described a generic system architecture for FMS; there is also briefly explained how to configure the different resource modules that actually control the tasks of the physical device and put together a work cell consisting of other FMS resources. Using the principles of distributed object technology there could be implemented each resource in the work cell as a distributed object. Finally, an example on building a FMS using a hierarchical approach is presented.
Elements Design of the Equipment for the Closing of Shock Absorbers through the Rolling Method
2015
The objective of this paper is the design of some elements of equipment for the closing of shock absorbers through the rolling method with a wide range of tank tube lengths and also of the functional structure of the equipment with the shifting/settlement of the damper in the sertization process. Closing damper device is intended by the deflection of the upper reservoir tube.

Study on Improving the Functional Performance of Linear Motion Systems
2015
In the construction of high performance mechanical transmission with high precision in movement and positioning are used ball screws with preloaded double nuts. Among the factors that influence the performance of these transmissions are friction idle torque and friction load torque. Because, theoretically, the friction idle torque is influenced only by the preload force that loading, the double nut of the ball screw, was experimentally determined dependence of that torque of screw speed. Given the set was determined and exposed in the present work, the relation of dependency, idle friction torque, preload force and screw speed. From the relationship thus obtained can determine the instantan…
